All completely valid points... I didn't consider the ball-handling element as much as I should. An interesting thought experiment, nonetheless.
The Ryan Kelly comparison is probably much more valid, but even Ryan was quicker and, perhaps more important, longer (at least I believe), making him a more natural stretch 4 at the pro-level.
I feel for Matt because his body fits the style of an NBA 4 from 10-15 years ago, but now he's almost a "tweener" between a 4 and a 5 in the modern NBA (just like Singler was a "tweener" between a 3 and a 4 ten years back).
Given that I'm still cautiously optimistic he returns for a junior season, especially if the current mocks stay cold on him. He can still carve out a role in the NBA as a big with below-average rebounding/defensive potential but sky-high shooting abilities. He just probably needs to show he can do that consistently before an NBA team will take that chance.
That said, I'll add in my caveat with all of these discussions, which is if Matt somehow starts playing well enough that he vaults into the first round conversation that can only mean good things for this year's team, and I wouldn't fault him for leaving
