Is John Wall going to be a big disappointment?

He can jump, he can dunk, he can cross over. So can a lot of guys. He's also pretty small. So was Allen Iverson, but besides that you don't see a lot of short guys ruling the NBA. Shoot first, p second point guard is what I'm seeing. Not to mention he looks like he's got an attitude. Every time he scores he looks like he just killed a beast by himself, what a man. Is this guy really all that, or is he more of another Shannon Brown?
