I'm in the minority here...
...but I think there is a decent chance PBJ comes to Duke. He's listed as a SF on most sites, and while I understand Coach K loves taking big SFs who can shoot and repurposing them as PFs, the truth is PBJ's shooting at the 3 would produce just a nasty shooting line up at the 2-4 with an enormous 5 and a quick 1. A starting line up of Roach, Griffin, PBJ, Banchero, and Williams would be frightening.
Defensively, this team would be pretty poor at M2M, but zone would be fantastic. That length, athleticism, and quickness would be destructive.
This team would be top 5 offensively and top 20 defensively. That's a top 3 team in the country.
