Supposedly his injury is minor. This is one concern i have with him though. Players like Iggy and Jason richardson had injuries derail them. Players that are as aggressive as brown taking it in the paint sometimes get hurt. They aren't all warriors and as durable a workhorse as pierce was. Pierce had a great midrange game to go with his ability to drive and get to the line.
Yeah, you really have to be able to shoot outside, too. Which is not to say that Brown can't.
I wouldn't put too much emphasis on him next year, however. 19 yo kid.
