From the two games I DVR'd he played a few minutes in each game, bricked a couple shots. Only impression I had when watching the game as a whole-- he did not stand out as being an NBA caliber player, which was disappointing to see (Melo, Sullinger, JaJuan Johnson looked much better).
From what I've heard in off-season interviews and articles, it sounds as though he's backed himself into a corner where he thinks he has to shoot his way into the league. He has an NBA body of a 4 man but tries to play like a small forward (face-up game only, hovering around the 3 point arc, doesn't try to rebound, gets bodied by PJ3 in the post). My 2 cents-- I'm a huge Brackins fan (he was all we had when I was in school) but I have 0 faith that he makes an NBA roster this season after watching summer league.
