JP is the best either hand shooter (not counting PGs) that I have seen in a long time.
I think he has to be developed at the 3, I do not see him playing PF. Could he play there some, of course. But I do not see the physique for that position as a freshman.
He will absolutely not get the number of minutes KC got as a freshman. (There are a lot more bodies with experience at his position!!!)
He did not shoot a bunch from 3, so it will be interesting to see how confident and accurate his stroke is as a 3 point shooter at the P5 level.
He does look good in traffic and finishing at the rim, but that is at a HS level.
His minutes (at TN, if he comes here) will be determined by his work ethic and defensive ability - not his offensive capability.
Assuming no injuries, and everybody comes back .... anything above 8 ppg is gravy.
