Andy Dalton is PFF’s 2nd highest graded passer this season

The other names are really good QBs that are having a good season. I don't need a metric to tell me that. I've watched every snap of Dalton's Saints tenure. He is not top 2 under any metric system. That's why it's a joke. The line about excluding red zone plays proves it. He's garbage in the red zone.
Red Zone only thing that matters. Easy to move between the 20s. Teams don't mind giving up long or even quick drives that lead to FGs.
