I think Mivid12 is right, in that, after 12 years, this does seem to be KD's ceiling. But, at the same time, I also think KD is the best we can do. This seems to be Akron's ceiling.
Our recruiting is good by MAC standards, but poor if you want to be "the Gonzaga of the east." Losing out on our very own home-grown Jayvon Graves to... Buffalo () is one recent evidence of this. Losing Jayvon is a kick to the nuts, especially considering our PG's being perpetually undersized & un-athletic. I knew we should have offered Jayvon when he was a sophomore.
Though you can't tell by my tone, I'm an optimist. Though we lose height next season, we should be more athletic. Antino, Ivey, Utomi, Parrish and Isaiah Williams are all athletic players who should be able to get to the basket off the dribble; much more athletic than this year's version of the Zips.
Who could do better? That's impossible to answer, really. I'd keep KD until he's ready to retire because I don't think we can do better.
