Their level of competition is unimpressive, but Joe had a couple FBS fball scholarship offers(Tulane being one). He's been All State on both offense (DQb) & defense (FS/Spec Tms) all 4 yrs in HS. Jimmer was a talented fb ath in HS as well(@ wr-quit after jr season), but not as talented as Joe.
I think Joe will be a multi yr All Conference player at 'Cuse(providing he plays 3 or 4 yrs), but I doubt he'll ever have anywhere near the statistical dominance Jimmer did, nor accolades (Naismith). Mainly because the level of competition and equally talented teammates.
I believe Joe has the potential to be a better NBA player than Jimmer though, as he's abit more athletic and a more diverse all around bballer.
