Horace Grant is this kid's upside. At least that was Doc's opinion on the first day of training camp. That would be thrilling.
He qualified that by saying that he (obviously) wasn't Grant now, but with his tools, that is the type of player he could become.
JJJ dropped in the draft, especially because of his lack of bulk. His lack of bulk, though belies his strength. JJJ can bench 330 lbs. Check the other combine numbers. How many other college players who participated did that?
I also remember a certain PF/C out of UMASS in '96 who was even less bulky and less strong than JJJ, but was about the same height and weighed about 10 lbs less when he came into the league than JJJ. And Camby wasn't a good free throw shooter. He did OK.
I believe that even given our depth at PF, due to our lack of a backup to JO, Doc does PF/C by committee and JJJ gets more PT than most of Doc's rookies and gets a great chance to show us what he can do. His four years at Purdue helps him in this regard.
People have to get off the myth that 4 year players have no upside. This kid has it.
