Sorry i don't have much more and i don't really know the kid. Comments are from watching limited pick up which, as we know, doesn't always translate.
It is apparent that Brown loves to use his exceptional hops going for rebounds and his quickness on defense. Is he big and strong enough to guard the 4? They might try it some. He's about Bryant's size, probably not quite as strong, more athletic, and looks defensively rather than offensively oriented. In pick up, he went out of his way to match himself up against Mr. Triple Double. He didn't stop him but he was a willing and energetic defender.
But this is pick up and very limited data at that. Won't forget how so many, including Dave Rose, JT, me, and others, overrated Corbin Kaufusi as a new RM. Chris Miles said it would be a different story when he had to play with refs and within a system. Miles was right.
We've seen promising wings drill 3 after 3 in summer and then couldn't do it in prime time. Seljaas did.
OTOH, Skyler Halford looked like the best leader on the team during the summer before his senior year. Turns out, he really was that good.
As Joaquin Andujar once said, "it can all be summed up in one word: youneverknow"
