His shooting % is dramatically impacted by the fact that he takes a lot of deep 2s and 3s. He is not an optimal player for Stevens' system (as far as I can see), who doesn't run a lot of isolation for bigs on the post. I would like to see a little more of that for Sully, at least.
I call BS.
It is affecting his shooting % because he is missing them. No one cared when he was hitting them. A lot of NBA guys can nail those shots. Who's fault is the fact that he is taking long threes, do you see anyone putting a gun to his head? I don't. In fact, at the beginning of the year, he was taking less and shooting better. Shot selection is a big part of any player's FG %. Smart players take good shots they can make, they just do not take a bad shot for the heck of it, but Sully does and he wants to be the hero, you can tell it.
I really doubt Stevens benching him lately has to do with the fact, that he told him to take and miss shots. He is expected to hit shots and select ones he can make.
The reason we do not run iso for bigs in our post, could be because we try to spread the floor for movement. Another reason if we do not have good low post bigs.
Sully is good off rebounds, but he lacks lenght and athletic abilty, he always has, and this hurts him in the low post. Few have better hands and are more solid at tip ins or put backs. But his post moves are pretty basics, back the guy in with his fat backside or the hook. Not like he has a slippery eel up this sleeve or the like. He can't shoot the turnaround that well because all a guy has to do if slide up on him, and it is trouble because of lack of length and vertical. The up and under does not work for him because he would not back up with his balance that well.
Sully might do ok in a system that is more half court in nature.
