Well these grades were missing and I volunteered myself to do them. My recollection of the game is a fuzzy right now, and this game was very hard to watch very often (plus things at home distracted me at times), so I welcome further input and contributions in the comments. This review is coming as a community service.
Kawhi: A
The game would have been a blowout if not for him. He did a number of Jimmy Butler and was unstoppable at times himself. He nearly willed the team to victory but not quite. Basketball is a team sport and his teammates didn't show up to play for his one.
Lamarcus: F
Terrible game for him. One of a successive trend of very low scoring games for Lamarcus. His shot wasn't falling and he wasn't aggressive trying to get inside. I remember seeing at one point Pop call up a play very close to the basket for him and his jumphook didn't go in. He's not drawing fouls either which means he's not being aggressive enough. This has been a trend in a few recent games and it's a huge concern. Is he still out of shape? What's going on with him? Does he need to close his tweeter account again? He had 4 blocks here, and was active on defense at times, but it wasn't enough.
Gasol: D-
He scored more efficiently than Lamarcus and grabbed a few boards in this one. For that he gets a bit of a higher grade than Lamarcus. However one cannot shake the feeling off that Gasol is empty calories. There were many plays at the rim that he didn't prevent from happening and at times there are layup lines with Gasol out there. Ugly.
Tony: D+
I was glad to see a spry Tony, but Rondo did a number of him, getting to the rim at will, scoring efficiently and almost finishing with a triple double. Tony himself made a few shots that were encouraging. He got to the basket and had a teardrop I remember. Still, he wasn't efficient with his scoring, and nothing really stands out in this game.
Danny: D+
I don't remember Danny that much, so this grade is almost by default. I apologize for that.
Lee: C+
He came in with a lot of energy in the 3rd Q if I remember correctly and was part of a run the bench made. He showed fire and leadership with the team behind big time. However, he had a few lapses on defense and allowed layups at the rim on the other end as well. Overall, his was one of the better games from the squad so it's hard to dock him that much, but it also wasn't enough.
Dedmon: D
He made mistakes on this one, fouling unnecessarily a jumpshooter with an overaggressive close out. 4 fouls in 13 minutes has to dock his grade a bit. The bench started the game playing very discombobulated and I think that doesn't help Dedmon's game. He tries to cover up for everyone and it doesn't help him to play defense under control. Still, his play is on him, he has to do a better job to keep his fouling under control. He grabbed a lot of rebounds in a short amount of time and that gets him a bump from F, but this was a forgettable game for him.
Mills: A
He singlehandedly kept the bench up at times with his amazing 3 pt shots under hard close outs. He came to play and made tough shot after tough shot. He was active on both ends.
Simmons: D+
He can't shoot and at some point that has to affect his grades. He just cannot make a jumpshot lately. He also missed a runout easy dunk due to wanting to show off? His energetic plays got him a few steals and he was disruptive on defense drawing an offensive foul on Wade. His defense gets him a bump in the grade but he has been very inefficient scoring/shooting. I thought he should have played more than Ginobili in this game, even though he could not buy a bucket (bc neither could Ginobili)
Ginobili F-
I have been vocal with concerns that he's done and it's going to be Kirby levels shooting. I hope to be wrong with that TBH... but this was a horrible game for him and I think his play was one of the reasons the bench was playing so unsettled early in the game. 0-9 overall shooting. His + plus/minus is more a result of the work put in by Mills and Lee.
Anderson: Inc.
1 rebound in less than 1 minute. Still not enough to see here.
Pop: F
IMO he should have gone further into the roster and played Bertans and Anderson at some point. The game was getting away anyways and since guys were not making shots, he could have looked elsewhere. As an early season game, he could have experimented more than he did. Bertans helped in the Bucks game and Anderson played well in the Minny game. Since Dedmon was fouling up a ton, why not try Bertans? Manu was having a horrible game and shooting blanks out there, same as Simmons why not try Anderson? He just didn't do enough... even for all his tinkering, he didn't tinker enough. He's not guilty of the guys poor play though, but he stuck with guys that were having a bad game a lot.
