Should I just lose like a man on Bengals +3.5?

Should I just lose like a man on Bengals +3.5? Now we know there hasn't been a bet placed on the Bills yet this week. Why would there be? It is not like they've played well the first few weeks. It is a sharp bettors party on the Bengals this week. What a fantastic situation they're in at home with their underrated D (shhh don't tell anyone how good it is) and Dalton he had a 300 yard game. And the Bills? After a big division game where they pull the upset (and really they're not that good anyway) they are due for a huge letdown. Can anyone provide a football reason why the Bengals would beat the Bills or even cover this? Or were those the reasons above? Brady threw 4 picks against the Bills and I know a few of them bounced off a few guys but actually that is what the Bills do on their pass D. Byrd and Wilson are sort of good at that although they did less last year I think. Dalton seems really ripe to throw some interceptions IMO. I know you could run at the Bills in other years and they gave up big yards but they must be better now. Perhaps the Bengals can do some of that. I fear the Bills are just way better at QB, will make plays in their secondary and somehow will find a way to make a few offensive plays against the Bengals and score. I don't think there is that much look ahead because they have a tough schedule after this game and I'm sure they're aware they need to win this one. But I'm on the Bengals. Help!
The best reason for taking the Bengals at +3 1/2 is that this game will be 2 1/2 by Sunday. And reason #2 is that they are playing the Buffalo Bills. Don't let three weeks of football cloud your thought process.
Well it worked out. I haven't seen anything from the game but it does look like the Bengals were able to run the ball on the Bills which has been their problem on D for a few years. I wasn't too happy with INT TD but did figure Dalton would be a risk to throw an interception or two in my earlier post and in a 30 minute game it would have been trouble. Certainly +3.5 was alot of comfort late in the game so ultimately your reason was the best one. I did feel the Bills would win this game but my early indication is that they obviously weren't as successful offensively today so the Bengals D is not going to be as much a secret going forward. Kudos to the sharp bettors the Bengals had enough of a team to take advantage of the good matchup situation to get it done.
