I'm going to take a shot at this. Do with it as you will.
The excessive dribbling, turnovers and not passing the ball back out drives me crazy too. But at this point in the season, for Ali to still be doing this tells me he is doing what Groce is asking of him. Or at least good enough at this point to stick with it. And that is to back into the paint to score or draw double-teams and collapse the defense. Remember early on Castaneda and Clarke could not get going north and south. And Trimble couldn't get his shot off. They would all dribble, dribble, dribble the shot clock away up top. Without a crafty guard this year who can get inside at will and cause havoc, Groce decided to use Ali as a point forward. (He did the same thing with Malcolm Hill, SF, at Illinois when we had point guard issues)
Now, Ali isn't efficient at this yet and going against a very strong, physical Buffalo team was rough on him yesterday. Ali is playing out of his comfort zone and is taking the abuse for the team. The double teams on him in the post opens things up for everyone else. That's what I tell myself anyway. Now if Ali would to spend the upcoming offseason living in the gym and gain 20 lbs of muscle he will be an absolute nightmare to guard. He would be able to back players down more quickly and easily. The game would slow down for him and his ball handling and reading of the defense would vastly improve. Allowing him to feed his open teammates on the perimeter. But right now he is head-down and battling. And his frustration gets the best of him at times. Bottomline, his post-game is definitely a work in progress, but this point forward has a very high ceiling.
