But again, Caleb Swanigan is not Blake Griffin. Blake Griffin had two back to back 20+ 20+ point/rebound games. He had a conference game where he scored 43 points and had 20 rebounds. It's not a knock on Swanigan whatsoever - which is why I said if he came back next year, he'd be on that Blake Griffin, Glenn Robinson, etc. level. Also, Oklahoma was a top 10 team and a #2 seed in the NCAA Tournament. This is again why I said if he came back, he'd be in a very similar situation as a Glenn Robinson, Blake Griffin, etc.
Caleb is a VERY good player and one of the nation's best - this isn't me knocking him. Not sure he's the best player in the country this year though. He's close, no doubt about it.
As for next year, Purdue is playing in the Battle 4 Atlantis, which is one of the best preseason tournaments. They'll play the ACC team as you mentioned and would likely play one of the Big East top teams as well, as well as Butler. Our non-conference schedule will be MUCH better than it was this year and the Big Ten will likely be better as a whole as well. It would be a much bigger stage.
Will it matter to him? I absolutely have no idea.
