That or they actually have a good defense that has bailed out the out-of-synch offense.
"This bad of a team" is laughable. The Patriots are no where close to a bad team. They're not lucky to be 4-0...they're just a better team than the Bills who blew a lead, the Jets who looked 10x worse than "this bad team," they put a pretty good game up against the Bucs and then they shut down the Falcons for three quarters and held on when it mattered.
That's not luck, that's football, and it's getting annoying to see people keep saying that.
That said, I expect the Bengals to win. Talib Vs Green will be an awesome match-up to watch, but the big story is the Bengals running game Vs the Patriots D without Wilfork. And whether Gronk and Amendola play. And if Collie gets another concussion.
