^ That's a reasonable enough assessment, although even bouncing back from injury, I don't see West's TS% dropping down into the 50-51 range, or even the 52-53 range. The last two seasons, he's been around .560, and he hasn't been below .532 since his second year in the league. I also think that West will continue his above-average defense, especially sandwiched between excellent defenders like Varejao and Iguodala.
One of the things that West has going for his is that he doesn't rely solely on athleticism to score. He's a very solid jump shooter, which will continue to open things up for him and his teammates.
EDIT: That's in reference to Who's comments above.
