Steve Slaton or Willis McGahee?

Okay, I'm deffinately starting Ronnie Brown, cuz I figure Dolphins game is gonna be all about the run without Pennington. After that, I'm not so sure. I think B-more will try to run the clock to keep Brady off the field, and McGahee has already proven that he can get fantasy points. However, I think that Oaklands p D is much better than their run D, so I see Slaton finally possibly breaking out of his slump. What do you think?
