Nice post, TP.
Well...
1) He is getting pretty consistently doubled, or having the D sag his way.
2) When he does fight for position, but doesn't get the ball, he goes and gets it - which means on the perimeter.
3) He looked gassed by the 4th quarter, so fighting for position would've been tough.
4) He sets more screens than anyone in the league, many of which lead to a pick 'n pop with him and Ray/Pierce.
5) When he is shooting his jumper so poorly, the defender can sag ever so slightly and take away any pump fake & drive move.
6) Gasol is staying inbetween him and the basket and KG isn't using any of the low post moves I've seen from time to time from him (up and under, pump fakes, jump hook... took one jump hook yesterday and made it effortlessly).
