I Think that he has the best shot from the key. Problem is that with his knees and loss of "lift" he sometimes doesn't get it on the apex of his "jump" so it's off. I also think it's refreshing to see him get back to being "the big fundamental" in the Post. He seems to just have forgotten about getting position with his body and attempting a measured jump hook or the other nuances of low post play. To many times this season he has just made a move and flailed his arms, looking for the call instead of getting a quality shot off.
Overall I think its best you're post players play in the "Painted area" most of the time and I don't want Tim being like Gasoll or...lord help us if he was, Dirk and chucking shots from distance...
Its fine an good as a "change up" but no he is more effective doing work down low and being in position for rebounds
