I think I'd keep Brees for sure. That D isn't very good and it's a great thing to see Brees playing from behind racking up points. I'd probably lean Rivers for the second guy just because their running game isn't all that great right now and a lot seems to fall on him. Bengals seem to have a pretty good ground game with two backs who can do it two ways. That said, if you can trade Rivers and get more for him than you would Dalton, I wouldn't have an issue keeping Dalton as my QB2.
