I know I'm probably being a negative nancy but I think the score is going to be close.
Dolphins are ranked #4 in the NFL running the ball. Granted, Bush is (probably/maybe) out which helps alot. Cards are ranked #17 against the run. I think Miami is going to just run all day and throw some play-action on top of it occasionally. Control time of possession and punt when they have to. No turnovers is paramount for them (and us).
Miami is also 3rd stopping the run, so I think we're going to have rough sledding once again, leaving it up to Kolb and our oline not to make mistakes. That being said they're 29th against the pass, so Kolb and Fitz and Roberts could have a huge day if they play mistake-free.
I think we'll win, but it's going to be close if Miami is able to control time of possession, and statistically they should be able to do that. And if there's ever a game when we don't need Beanie, IMO, it's against Miami since they would probably shut him down. Look for RW and Howling to have several catches in the flats, leak-outs, etc. Seems like a trap game to me, and I don't know that we match up as well as we'd like.
(Edit: My prediction 13-10 Cardinals)
