I'd really like to see Kyle develop a post-up game. Ala a Chauncey Billups, We saw him bust it out a few times but I think if he honed it would really diversify his offensive game. Everyone is saying how Kevin Mchale will really help our big guys play better in the post since he was also a bit undersized but the same could be said of Kyle.
As far as his defense goes I think he's pretty well set (get it?) there.
