I could very well see the Dolphins and the Patriots both losing today.
Patriots because the Bengals seem to match up well. 2 good corners for Moss and Welker, and an offense on paper that has the potential to be explosive against the Pats iffy defense. Pats should have to outscore the Bengals today, and I don't think they can do it.
Dolphins because the Bills should be able to run on the Dolphins. No true Nose Tackle, a rookie at DE and OLB, Cameron Wake was limited to pass downs last year because he's a one-dimensional player. I look for a big day from Spiller. Plus, The Dolphins have a history of starting slow under this regime, and I don't trust Henne much. I just think the Bills can hang with them this game and could very well pull off the W.
I'd say the Ravens over the Jets but that actually wouldn't be an upset. I expect the Ravens to knock Suckchez's teeth out anyhow. It's not like the kid is a threat to actually win a game on his own anyhow.
