I wouldn't say that Sully's post game is overrated. I actually think he's very good in the post - he has a nice set of moves and a soft touch, finishes pretty well through contact, etc.
Every year since his rookie year Sully's three point attempts have gone up (from 2% -> 23% -> 26%). Subsequently, his shot attempts inside the paint have dropped proportionately (45% -> 31% -> 27%).
Many people excuse this and say it's purely because Brad has pushed him to shoot more three's - if that's the reason then fine, and it explains the change.
He also had a respectable 28% Free throw rate in his rookie year, which indicates to me that defenses were respecting his post game - this has since dropped to 18%.
Again this makes sense, because jump-shooters tend to not get fouled that often so that can all come down to Brad's insistence that he shoot more threes.
BUT
What it doesn't explain is why his actual FG% inside the paint (not only his number of attempts) has also dropped significantly. He shot a very nice 67% inside 3 ft in his rookie year, but only shot a pretty 'meh' 60% and 62% in the following two years.
Why??
I find it hard to believe that he's simply lost his touch in the post, so I don't know how to explain this.
All I can conclude is that all of this is a result of conditioning. Guy gets tired, doesn't have the energy to bang in the post and absorb contact anymore, so misses more inside shots - decides to preserve energy by stepping out on the perimeter more and taking more jumpers instead of attacking the basket.
As a big guy myself, I tend to find this I get stuck in this same pattern when I play. At first I'm hitting shots, driving inside, etc. After a few times up and down the court I start getting tired, my legs start getting weak, etc. First thing that happens is I become less aggressive running back on D. Next thing is I start moving less on offense - I drive and post up less, tend to start settling to open jumpers when I get them. Finally the last thing that happens is my legs get weak so I am not getting the usual lift, and I start missing jumpers.
This all sounds very much like what seems to happen with Sully, so I'm wondering if all of this is just a result of conditioning.
