I thought Jahlil Okafor was the early runner for the #1?
he's up there too, but this guy is projected by nbadraft.net and I believe draft express well as #1.
Draftexpress still has him as #1, I don't read NBAdraft.net - their analysis leaves a lot to be desired.
Not to hijack your post, so I'll get back on subject. It's interesting that Emmanuel is going the Brandon Jennings route. I don't think it'll help his development though unfortunately. Brandon hasn't exactly been a success story and the only other guy I can recall doing it - Jeremy Tyler - seemed to struggles a lot with adjusting to the NBA.
