Final Four 2016 (I)

Photo: Euroleague.net
It’s not the first time I say it, very often we try to find the “key” for the outcome of a game. We go to the statistics, we talk about this or that defensive modification, a beautiful set play drawn by the coach, a player in bad shape or a great offensive performance. 

Sometimes we make things too complicated and sometimes we try to over simplify and find one reason to explain why the game ended as it did. The truth is: there isn’t a single key when it comes to sports. That makes it, specially basketball, amazing and unpredictable.

There were so many details during the CSKA - Fenerbahce… It would take days to run through the game trying to understand in deep every single action. So, I will just bring some of them, and I hope we will be able to enjoy in the next years many more games as good as this one.


As they pointed out in @Euro_Adventures podcast that fifth foul might have been one of the luckiest strikes in the last years. Vorontsevich was fouled out and that brought Khryapa back in the game. His performance during the last ten minutes has been praised enough by now but, was he supposed to be there? was he supposed to sub in during the last minutes of the game? We will never know, but a situation that could have been really negative for CSKA turned into the best momentum for them to win the trophy. If that doesn’t make us think as coaches...

The game started with an interesting match up, Kalinic guarding De Colo. Probably to switch ball screens slowing the french down, while avoiding mismatches inside or in the offensive rebound. Seven CSKA points and two personal fouls on the Serbian (who had to be substituted) gave the first “victory” to the Russian side.


It is a frequent topic in this blog, I’ve written about it here,  here,  here,  here,  here, and not many days ago here. So it is no surprise to see teams switching in several ball screens. Having players like Kyle Hines (also frequently featured around here) or Udoh helps a lot. We saw many fantastic defensive actions from these players in the final game of the Euroleague season.

I counted 13 situations where Hines switched defending ball screens. Do you know how many points did Fenerbahce score against him? Zero. Not a single point scored by the “small” being guarded by Hines in those switches. Fener scored two points off an offensive rebound (Vesely against Kurbanov) and that was all in 13 possessions. Obviously, there is a team effort there, other players are involved too, but having Hines is an insurance in these situations.



We’ll keep talking about this game in the next post, stay tuned.

CSKA Switching

Photo: Euroleague.net
I won’t pretend to explain a defensive game plan because not having enough information about it, but I can show you some details of CSKA’s defense during the third play off game against Red Star. If you want to get a deeper understanding, my advice is to analyze those three games to find out how it works.

There’s an old saying in basketball “the best man to man defense looks like a zone and the best zone defense looks like a man to man”. That could be the idea behind the defense we saw in the mentioned game. We can argue about the way we call it (switching man to man, flexible zone, mutant defense) but there’s no need to go crazy about it. 

In my opinion, CSKA has the personnel to try this kind of switching defense. Their physicality and size allow them to go for it not giving up a lot of advantages to their rivals. But there’s another idea we should keep in mind. The defense’s “first stone” is not the switching, but the 1 on 1 and team communication. Bigs need to make efforts to guard smalls and smalls need to be really aggressive, as they will find themselves in a quick mismatch situation quite often. Then, the focus to switch or rotate when needed is also a must.

Also, the scouting work matters, Red Star use very often “horns” situations, as well as quick side screens. This switching defense may create problems and definitely slow down the rhythm of the offense. 

Some of the rules they appear to be following:

They place a “big” on top of their defense (Kurbanov, Nichols)

They switch high ball screens avoiding an advantage for the “roll man”, and try to keep a small guarding the ball after the first switch. 

Continuous attention to the ball’s position and players’ movements

Be aware of cuts, to follow and/or rotate, trying to stay in the same lines. "Smalls" defending outside spaces, "bigs" close to the basket.

Sag off from your man when the ball goes inside

If the mismatch finally happens: FIGHT IT. No easy penetration, no uncontested shots, no easy passes inside (defender in front) Off ball activity.


Let’s take a look:

Final Four 2015: Cool Goudelock Down

Photo: Euroleague.net
A lot has been said about Real Madrid's offense in the semifinal against Fenerbahce. Not so much about some defensive details during that game. It is clear that their offense was flowing big time, the ball movement was great, they shared it the right way, the quality of the passing absolutely delicious… But they did some good things on the other half of the court too.

Let's take a look at how they cut Andrew Goudelock's rhythm during the first two quarters of the game. But first one more example about something we've been talking about lately, numbers. You can check Goudelock's points and immediately think that he was dominant (34 minutes, 26 points, 9/11 2PT, 2/6 3PT) But, if you want to dig a little bit more, you will find out how at the end of the second quarter, he had 6 points (2/3 2PT, 0/4 3PT) while his team was trailing by 20 (55-35) and the game was really far from where Fenerbahce would have wanted at that moment…

From the outside, and not knowing first hand what was Real's game plan, it looks like they paid good attention on Goudelock, probably the best 1x1 player in the competition. Let's take a look at some clips:

In the first video, we can see Fenerbahce playing one of their most frequently used sets. They set a down screen and then they play a hand off pass. Not only the player guarding Goudelock is committed to the task in hand, but also the other players are really aggressive. Real gave up some other options while trying to decrease Goudelock's production, which is normal when you focus in one player.


I was talking about cooperation to stop Goudelock before. In the next video we see that team work again. Two clips in which we can see up to three of Real's players (and in the first clip, a fourth giving a hand too) guarding Goudelock in the same play. Yes, he scores in the second one, but every effort counts and they keep making his life a little bit harder with their defense.


More examples, hand off and ball screen situations. We see how the screener's defender is aggressive to stop Goudelock. Aggressive hedging, and again, it is clear that they rather prefer other players to have the scoring opportunities. Help side defenders work against those other options, trying to avoid the easy shot, forcing some drives, rotating…


The last clip might seem naïve, but it is not. A "no helping" policy is advisable when facing some players. It appears Real Madrid decided to use that strategy with Goudelock. There were some actions where helping would have been a right move in a normal situation, but the defender decided not to. Take a look at the next clip.


So let me ask for your opinion: Was Goudelock's defense a success?

P.S.: You can check all of Goudelock's first half actions, here.

Final Four 2015: Ball Screen Defense - Switch

Photo: Euroleague.net
I'll be posting in the next days some details we saw during the Euroleague Final Four. In my opinion, it's been an amazing weekend for European basketball, with really good basketball and a good dose of thriller... 

We've been talking about the 21st century basketball for a while, its evolution, the way our sport is going… Maybe this Final Four has been a clear example about the "new basketball" we are going to see. 

I'm talking about defense now, and specifically about switching against (ball) screens. Will this become the main defensive rule in the years to come?

During the semifinal between Olympiacos and CSKA, we saw how that defense was extensively used by both teams. I bring today two short videos with the teams scoring... 


...and getting stops. 


Both single (between the two players directly involved in the screen) and multiple (different rotations to avoid mismatches) switching options were played during the game. It's no surprise that many teams are building their rosters with this idea in mind, trying to find players as physical as possible, capable to play solid defense in different situations. Other teams work on ways to switch with "smaller personnel", and still cut the offense's rhythm. 


What's your opinion, are we going to watch more and more switching?

Final Four: Bjelica's Corner

Ball screen actions, probably the most frequently used tactical tool in modern basketball, is extensively studied on both sides of the court. It will be one of the keys during the Final Four, as the teams that will be in Madrid excel in the use of this "art" and have terrific players to execute it.

It would be too long to analyze every single option we will find during the Final Four in one post, so this is a small study about one of them, which I think will be important in the semifinal between Fenerbahce and Real Madrid: Nemanja Bjelica on ball side corner and two smalls on the opposite side. This is often played by the Turkish team, and it will be interesting to see how it will work, and Real's defensive answers. 

There are different ways to approach a specific situation from the defensive side. For example, you can have a rule you follow no matter what (e.g. "whenever they play a side screen, we "trap") and you can also consider who are the players involved and then adapt the defense. 

Let's take a look at different scenarios (and let's consider the "1", "2", and "3" positions interchangeable. So I won't talk about "positions" but about characteristics of the players at each one). Always understanding that (in the opinion of many experts) the Euroleague's best "stretch 4", Nemanja Bjelica, is in the ball side corner (he is "4") 

For opposing teams, it would be wise to avoid 4's defender helps against 5's roll (giving room for Bjelica to receive a quick pass): it is an extremely dangerous situation, Bjelica being a huge threat. He can catch and shoot, and he can drive to beat the defender's close out.




If the defense manages to avoid these two situations, they often play a "5 x 4" ball screen which creates a new advantage either for Bjelica to score, or for their "5" to roll hard when he has an advantage or crush the board when Bjelica drives.


Allow "1" to shoot, go under the screen: if you rather prefer that shot (e.g. when the ball handler is not a great shooter) than any other option the offense can find. As usual, scouting and "numbers" will help in the decision making process. No helps needed, no "Bjelica's threat"



Do not allow "1" to shoot, go over the screen and collapse the paint avoiding penetration: this option should be considered when you think "2" and "3" threats are smaller than "1's". The screener's defender will try to stop the penetration. As helps will be coming from "weak" side (which we could consider "strong" side once the ball handler drives to the middle) those are dangerous shooting opportunities. And the player getting that pass may try to drive against the close out, so the defenders need to be ready to rotate.



Switch and defend the mismatch, or multiple switching: here, one more time, the defense avoids helping from Bjelica. One problem, Fenerbahce players are very patient to find the way to exploit the advantage. It can be inside, outside, or they can keep playing with very good spacing which usually leads to a good scoring opportunity. Having great "one on one" players makes them really dangerous in mismatch situations.




"Ice", deny the screen: so you don't let the ball handler go to the middle and you create a "traffic" situation on ball side. Fenerbahce can be either very aggressive or very patient against this defensive option. The "aggressive" option: as soon as the screener sees it, he cuts hard to the rim, while the ball handler drives baseline and attracts the screener's defender. Then he can find 5 or the wide open man on the side if there are long helps (a good way to avoid a quick roll is to bump from "2's" defender) Obviously you don't want to help from Bjelica, he is ready to hit the corner three! The "patient" option: the screener will pop and they will attack on the opposite side.




Flash / Trap against the ball handler: trying to stop the ball, being very aggressive to stop penetrations, force turnovers… Although Fenerbahce's spacing plus their high quality players helps them find a good option. First things first, you need to take care of the roll man. We already saw what happens when you help from Bjelica. So you're gonna have to work on defensive fakes and get back real quick after the flash.



A lot to study, many decisions to make, and a small post to show the kind of work coaching staffs are doing "behind the cameras"

Real Quick: Box Out Against Mismatch

One of the biggest risks when you decide to switch defending ball screens, is the immediate offensive rebound opportunity for a big man against a smaller player. 

When facing this kind of defense, realizing about the advantage for his teammate after an hypothetical missed shot, the ball handler can be even more aggressive to try to finish. He can miss the shot but they will have that advantage in the offensive rebound. 

Some players have that "instinct" and follow the action to get the offensive rebound (although in my opinion this is something you can practice from the very beginning of a player's career. But how many youth team's coaches practice offensive rebounding skills?)

So with that idea in mind, and trying to reduce the risk of an offensive rebound that will create a high percentage scoring opportunity, a key for the ball screen "switch" defense should be to box out properly in that mismatch situation.

And this is what I want to show you today, take a look at the video and notice how Nizhny's player Evgeny Baburin, right after switching in the ball screen, turns around and looks for the contact against the big man, boxing him out and making it easier for his teammate to get the rebound after stopping the penetration.

Ball Screen Defense: Switch And Rotation

Last night we watched a great game between EFES and Real Madrid. A tough one that ended up being decided in the last minutes. 

Let's take a look at some of the last plays of the game. Real looking for options off a middle screen and EFES defending it:

Real played this middle screen three times in the last two minutes of the game (in their last three set offenses) Sergio Rodríguez and Gustavo Ayón running the ball screen and Real's power forward, Nocioni, filling the corner on the left side, with the other two smalls, Carroll and Llull placed one on each side.




EFES defensive rule was clear: they switched between Ayon and Rodriguez's defenders (Lasme and Draper) and made a rotation with one of the weak side defenders when Ayon rolled to the basket. With that rotation, the mismatch after the pick and roll is not so big (it wasn't Draper, but Perperoglou or Osman taking care of Real's big) Perperoglou and Osman, both of them big enough to avoid a big disadvantage in that mismatch, were aggressive and managed to deny the pass to the big man.

Real played three different options after the pick and roll: pass for Llull (and another ball screen), pass for Nocioni (one on one against Perperoglou), and Rodriguez's one on one against Lasme (which finished with a turnover). Only the second one ended up with the white team scoring. That gave them two points in three possessions, which was not enough to win a close game.

Let's watch it:
