I'm guessing Brown and change probably does it. I have no idea what Bamba will be in the NBA; none at all.
Regarding Brown, he still has as many question marks as he does talent. Is he a star? I'd bet not. Can he play like a star sometimes? Sure. The question will be whether he can provide consistent production on a team where he will never be the man, or even second to the man.
And no, I don't think Rozier and the Sac pick is enough.
