Rashard as become a much better blocker in the last year. I honestly don't have a problem with him picking up the blitz. I do think Redman does a great job at it too. Now Dwyer, he's got some work to do in that area, LOL.
In all fairness Rashard should get the chance work with a decent offensive line because it's not like he totally sucks as a running back. However, who's to say how long the Steelers offensive line will play like they did last week? If they continue to shuffle players in and out, that leans more to a style like Redman.
