I am getting the impression the coaching staff like Begarin more than they do Yam. Or maybe like is the wrong word. Maybe they think Begarin more NBA ready.
Begarin was playing more minutes, more important minutes and most often with the 4 guys that were on the team last year: Pritchard, Nesmith, Langford and Edwards. Kinda makes me think he might be higher in the plans than Mader, as of right now
