Fes is the ONLY guy we have who actually at least slows down Aldridge. Millsap is absolutely helpless playing Adridge. Jefferson not much better. Fes is HUGE in the paint; not just tall, but also wide in the body AND with very long arms and quick hands for a big. Aldridge didn't seem nearly as eager to challenge Fes as he did Millsap & Jefferson.
Fes does have offensive moves, but he is very, very indecisive as to WHAT to do when he gets the ball; dribble, shoot, or pass. He doesn't adjust to his opponents' defense well at all.
The man simply needs to get better motivated and focus on developing an overall better and more consistant game. The physical skills are all there; his problem appears to be mainly between the ears...
