Keep in mind, he left Purdue when they basically told him he likely wouldn't start.

This is a guy who absolutely has decided he's going to be one and done. And it's going to be really hard to change his mind. Unless he drops a ton...but he probably doesn't, just due to the physical gifts and upside from underlying talent.

I'd plan on getting the most we can out of him in one year and anything after that is gravy
