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

It's funny how you guys throw around the phrase "backup quarterback." Andy Dalton isn't really a backup quarterback. He's thrown for well over 30,000 yards. He's been to a few Pro Bowls. Trevor Siemian "is a good backup." Andy Dalton "is an old starter." There is a difference!
Jameis Winston is "a young starter turned young backup." That's not as promising a career trajectory as being someone who started for almost a decade before becoming a backup. And notice he only backs up in situations where he ends up playing a lot anyway. Don't you think he came to the Saints because he thought he could beat out Jameis in training camp, or otherwise replace him in the season? Which he has done?
And you crack me up the way you analyze Dalton's game tape to find open receivers he missed. Do you use the same fine-tooth comb when analyzing the 31 other starting QBs in the league? Do you have any idea how often good QBs miss open receivers, or are you only doing this to Andy Dalton because you think he is nothing but a backup?
How many backups can play with the poise and consistency and general above-averageness that Dalton has played with all season long?
