Rod is a good back, he runs hard, he's probably doing things right now.  From the Cinci game it looks like he lacks vision in the hole.  I saw him repeatedly run up the back of his blockers head down only to barely hit the hole late or watch it close up as he hit it.  EZ on the other hand found that back side almost every time.  I had been clambering to see Rod get more touches he's huge and a powerful guy he absolutely blew somebody up at the end of a run.  But he left a to of yards on the field.
