I don't agree at all.
Bank the scholarship and use it on whoever you want. An impact transfer, a JUCO, another high school guy, whatever.
This kid is going to sit on the bench this year, maybe play some next year if we are lucky? And maybe get decent minutes his JR year. There's no reason to spend the scholly unless TJ think's he's a legit player.
Prohm's talk about finding a practice body concerns me and it's (of course) absurd to waste a scholarship on a guy just for a practice body. That is inarguable.
