From a defence standpoint, the Spurs are ranked:
| Opponent | Restricted Area | Paint (non-restricted) | Mid-range | Left Corner 3 | Right Corner 3 | Above the Break 3 |
| FGM | 6 | 3 | 28 | 10 | 30 | 18 |
| FGA | 8 | 5 | 30 | 8 | 26 | 9 |
| FG% | 3 | 4 | 9 | 16 | 30 | 24 |
So the eye test is right, we defend the 3s horribly, especially at the right corner and above the 3.
From what I recall, our help from drivers come from the right side when there is a player driving (because most players are right handed driving down the right) and Wemby is right handed so he is on the left. The problem is the driver already has a closer pass to the right corner so there is less time to recover. (see 10:56 in the clip below, where I have absolutely no idea what Fox was doing).
I don't want to blame Keldon but he is on the right side all the time as well, and he has a tendency of just vacating his man to either help, or worse, ball watch. See 10:35 or so in the clip below. We gave up a wide opened cut but Pod was also left opened at the 3)
For the top of the key stuff, it's just total collapse a lot of times. See 12:17 in the clip below. Fox was totally disengaged on the drive, forcing Wemby to help, which causes Castle to have to come and cover the left 3, but Champaigne is supposed to rotate to the top where he is late, but even if he did, the right corner would be wide opened as well.
12:36, double screen coming and Champaigne is looking at the second screen but appears he didnt' call it out. What should have happened, if they actually are a strong defensive team who knows exactly what to do at what point, would have been to swtich the defenders where Champaigne is now on the 2nd screener, Barnes go on Curry, and Vassell switch onto the first screener (cutter). Instead, we have a Champaigne and Vassell doubling Curry at the top of the 3 pt line with noone guarding the 2nd screener (is that Podz?), while the cutter has a wide opened lane with Barnes being too late to recover, forcing Wemby to rotate and leave Al Horford wide opened at the 3. The only thing that is right (imo) is Wemby came and rotate to help as a last ditch effort because he is the better shot blocker than Fox, and Horford is a further distance away from the pass, giving the defence more room to recover. At that point, Barnes should have been shooting down on Horford to challenge the shot but he was still chasing after the cutter (Butler I believe). Then Champaigne charged over to Horford to challenge but it's way too late and even if Horford missed, nobody was there to box out the second screener (Who I think is Podz) and it likely would have been an offensive rebound by him anyways, as both Barnes and Wemby are way too deep for a rebound off a 3 pter.
13:08. Podz screened curry, both Vassell and Kornhub stuck to Curry, leaving Podz wide opened for a 3. To be fair, you can't leave Curry opened and it appears Vassell got clear instructions to stick to Curry no matter what. If Kornhub didn't cut off the Curry drive, it would have been a wide opened 3 for #3 at the right corner from a Curry kick out, so choose your poison.
I just randomly started at around 10 minute or so of the video and there are issues with every one of them in terms of defending the 3. Good news is that these are easy concepts to manage.
