I like BHam. But I think his ceiling is a discount DeMar DeRozan, who in of himself is sort of a hotly debated player of wildly differing valuation and he's a long, long way from that ceiling. He's got a smooth athleticism, but had problems finishing around the cup in college which generally doesn't translate well to finishing in pro lanes. He improved his range from the outside, but still was only a 35% 3fg shooter in the MWC which doesn't sing to him being a pro offensive option. He improved on his defense and passing some, but is still incredibly left hand dominant on the dribble and didn't fare well when defenders took that away from him.
I personally think the extra year probably took a little money out of his pocket, but other than that didn't particularly help or hurt him as far as playing professionally. If he busts his ass and develops a crafty finishing game around the cup he will get an NBA contract because there is always room for a scorer on the bench. As thing stand right now he's a high volume low efficiency scorer from a mid-major conference without any particular quality that makes GMs salivate.
Compare him to someone like Rashad Vaughn. Vaughn was bigger, a better shooter, had more bounce, and was younger which gives him more of a 'potential' value. He washed out of the NBA in 3 years and after kicking around the G league for a year has bounced around the Greek and Ukrainian leagues where he's been a good but not great player and is currently not on a roster. He went 9th pick overall.
Compare him to Patty McCaw. Patty is bigger, a much better defender, a much more efficient scorer and shooter with more bounce and a better rebounder as well. And again, was much younger when he entered the professional era of his career. He was drafted 38th overall.
