I hope so because Sander was SO fun to watch. But i remember hearing (it was before the Internet was ubiquitous) how Jarrett Payton was lighting it up in HS, too. Then he wnt to Miami and was pretty average and spent a couple of years in the pros warming a bench (for Tennessee, I think?). I think the only reason he got a contract was based on name.
I think the becoming a good pro has less to do with physical ability (it'll get you in the door, but there are a lot of physical freaks that wash out) then mental fortitude and want-to.
I'm not saying this kid can't do it, I'm just saying it's WAY too early to tell. I hope in 5 or 6 years he's going #1 in everyone's fantasy drafts, though.
