I have been steadfast that people were wrong about Benson. Time and time again I would defend him, not because I thought he was an elite talent, but because nobody can run well or look good when your OL stinks. Look at Thomas Jones. People incorrectly think he is a really good RB. he is not, in fact, he has less than average ability, but he looks great when running un touched through huge holes. Shonne Green steps in and puts up 2 TD's and 150 yards after Leon goes down. Is he elite? The point is that great athletes can all look good or bad depending on their line. Sure there is a difference in the level of all backs, but do you think Benson would look as good as he has been if he were getting hit behind the LOS like the LT2 in SD?
I am not sure where Cedric's talent level is yet. He is looking good right now, but more important, Carson Palmer's deep threats and passing threat in general are opening up lanes for Cedric.
