Let's be honest. He's a shooting guard playing small forward. Against many (most) college teams that's fine. He's not as solidly built as Castle or McNeeley before him, but is probably quicker and more explosive than either of them.
I mentioned Alex going off once White was moved from SF to PF, well at the same time, the SF became McDowell most of the time, a guy who doesn't pose any size issues for Braylon. Not surprisingly, his minutes went up. Even White isn't all that big. I really don't want to find out what Caleb Wilson at UNC would do to Mullins. Bryce Hopkins would probably be tough for him to guard as well.
