I would tend to agree except I think the Colts defense may be that bad. Cincinnati has a better defense, but still only above average. The 5 defenses in the league that can keep the Colts and Cinci in reasonable check, all have solid offenses this year. The Colts and Cinci both have tough games this week, so we will learn more.
Cincy got really banged up last week and one of their best receivers TJ Houshmandzadeh is still questionable for Sunday. It will be a tough match against Pittsburgh, since a) they are playing at Heinz, b) the Steelers want to avenge MNF's showing, and c) they are intense rivals.
Though it will be a tough game, I think the Bengals win. But I'm certainly not an infallible prognosticator of the pigskin.
They can outscore most teams. Those teams won't be around come January.
