Amare basically played in a zone defense for 10 years. This scheme is a different animal.
I just hope he does improve there. Knicks need his offense badly, specifically for those stretches when Melo isn't on the floor. Even with JR...they're too shot happy, that interior presence (even off the pick and roll) will open things up like Melo/Tyson does.
However, instead of looking to return to dominance and put up 20+, if he can make an impact rebounding and defending, I'm sure everybody will be happy.
