Because he is a 6 foot point guard who is not very athletic. Is he gonna grow? Is he gonna be come more athletic? Like I said he's most likely a second rounder whether he comes out this year or next.
Because his skills improve with another year, and, more importantly, because he becomes much more visible on a team that would be potentially ranked in the top ten and which makes a run in the post-season. Without a post-season this year, Uconn and Shabazz are completely under the radar. Shabazz is currently averaging 17pts 5 assists/game. He also has a tendency to drift in the first half. If we got to the semis or the finals of the BET next season and to the sweet 16 or elite 8 with shabazz leading the way, playing complete games and averaging 25 pts and 7 assists, how could his stock not go up? It's the difference between being a second round pick or not being selected this season and being a first round pick next season.
