Having good defense with the Bengals is amazing, their defensive players mostly pathetic, so you should be giving us some defensive tips.
As far as offense goes, take what the defense gives you, if they are running mand, throw slants and outs, for zone, go down the middle or roll out and find the holes in the zone. If they are blitzing use some screen plays. The easiest people to play defense against are the people that are really predictable, so change it up a lot and use different formations and different plays in the same formation.
