I'm not as worried about Dow's skill as his understanding. Separating those two from each other can sometimes be difficult. Dow should experience a decrease in his fouls as he plays more...at least in fouls per minute played. This will happen by learning more and nto trying to do to much in the limited minutes. His skill issue I could see in very lmited minutes was his stance relative to passing and handing off the ball. He does need to develop his ball lhandling a bit. The other skill that stood out but may not be needed as much as his ball handling is his flat shot...where he tries to aim the ball. His playing time if increased should help with all of that, but even more in not trying to block shots head high, but to go up and get the ball after it leaves the players hands. He slaps down too much...and his positioning in help D can be tweaked a bit. All that and what is needed out of Dow I think early minutes will be important until the light goes off.
Wheeler...I hope has consitency in his shooting. Like all we hope he could get decent in driving the ball since his game would be helped. He did improve his hands inside on O where teh ball wasn't stripped as easy. I think his D improved last year as well. It was just that elevated jump in his perimeter shooting along with a bit of flatter trajectory that caused the misses to be bad misses. Everything he needs to improve is in his hands...nothing that cannot be improved.
I think we will enjoy the season more than last year. Purdue needs to have Dow or Edey ready to contribute meaningful minutes prior to the Big to make a run. I think there will be enough scorers that Dow will not be needed to score, but still has to score if ignored. He just has to improve his ball handling (passing and hand-offs) and decrease his slapping down on attempted blocks to help Purdue. He can't have turnovers that go for baskets at the other end and he can't put teams in a bonus too early.
Handle the ball screens which I think he can do and rebound without fouling...run the court and look for some quickdowns while requiring other bigs to run with him during his minutes.
