UCLA had several NBA defensive level guards on that team. Those guys never made it to the NBA because they couldn't score but they could defend. Jimmer still had his points in that game but 7 TO's was what lost us the game.
One of Jimmer's biggest problems in the NBA was he was a backup PG/SG who turned the ball over way too much. That UCLA game showed to me that he very well would have those same problems in the league.
