I remember back during the fall of 2013 when I declared Omar the best NBA prospect on the roster. Aside from this being a sign that I don't know what I'm talking about, it really demonstrates how significant his fall has been.
Certainly, he was nowhere close to healthy as a sophomore, and as a junior, he didn't play until, IIRC, the Duke game. I also remember reports from Duffy (or maybe it was Borges) during the summer of 2012 raving about how Omar was destroying practices, hanging with Kemba in one on one games, etc. If, somehow, he can return to pre-college health, that would be exciting.
