You're not just taking a 6'5 kid who can shoot, you're taking a 6'5 kid who can't do anything beside shoot. Can't play defense, poor ballhandler, definitely a sub-D1 player in terms of athleticism, with the last point serving to mitigate his one strength since he isn't athletic enough to create his own shot with any regularity. In other words, I think you're missing a large part of the equation here. If you're bringing in Stewart to sit out for a year, are you really getting your money's worth? I think it's pretty clear that he didn't have much D1 interest if he ended up at UT-Martin. I can't say that he didn't have any, but he sure as hell wasn't getting high major offers.
That's patently false (that he didn't have much D1 interest). Nevada, Maryland, Oregon, Nebraska, and KState all wanted him (each of those schools visited Parker directly in PIttsburgh). And he said from the outset that playing for his dad was possible--for personal, not basketball, reasons. Why do we have to disparage a kid just because he did something we wouldn't do? He was a good player who had a bright future here, and we haven't replaced him, unfortunately. Have we recruited better athletes? Yes. Better shooters? Not yet.
