Any QB currently on an NFL team could have beaten the Bengals with that defensive gameplan. On 95% of the snaps, the secondary and LB's backed up 5-7 yards which left a 10-15 yard hole in the middle of the field. That play was wide open ALL night.
The only play that Manning made that couldn't have been done by anyone else was the TD pass to Wayne.
Does that take anything away from Manning? Absolutely not, he's a great player. But don't act like Manning torched the Bengals. He took what they gave him. Anyone could have done the same.
