I agree with this on West. Terrific player and we could not have gotten anyone better for what he took to be here, but his fit is not the best in the second unit. He is similar to Diaw in size/rebounding/defense tools, but you can't trade Diaw out, bc Diaw in many ways is the engine of that bench, at times more so than Ginobili. Without Diaw in it, the bench would not perform as well as it does. What we need West to provide, he's not the best at. he's playing out of position and it showed, in this game, and possibly against others. There are the Bismark Biyombo, Tristan Thomsons of the world. Many young bigs make their mark as hustle/rebounder guys and even if they are not as talented as West, if they consistently get OBoards or easy shots at the rim, it will become a problem. He also didn't seem like the best big in the small ball style the bench played.
The really experimental lineup was the Boban,Diaw,Kyle lineup. In preseason we tried an even lesser lineup with Rasual Butler instead of Diaw, and still they did very well. Granted, it was preseason, and OKC is a very tough team, and Kanter/Adams are offensive/defensive big men who have started in this league and quite good at their particular strengths. But it feels like if you want to go full perimeter to get the better of them, the Diaw/West combo isn't it. Make them come out and guard Anderson and Diaw, make them deal with Boban inside. That is a really unproven proposition but if you want to truly go perimeter, go all in. The Diaw/West combo isn't fast or perimeter enough to punish big lineups and they get murdered. I wouldn't even call them fully a perimeter lineup. Food for thought.
