Yes, there are cries for "Pull Winston!" everywhere (on here, on Twitter, on Reddit), and they may be justified, but that's not my point here. All those cries seem to think that putting in Dalton will immediately bring win after win. People seem to forget that Andy Dalton, while he might be a great option as a backup, is exactly that - a backup. And he's a backup for a reason. Ask yourself this: If Andy Dalton had never come to to Saints, would you be clamoring to trade for him and put him in for Winston? Yeah, he had a middling amount of success in the NFL, but I'd still put him in the "serviceable" category of NFL QB's.
Fun fact: Andy Dalton hasn't had an above-.500 season since 2015, and that includes a 2-11 season in 2019.
It's an easy fallacy to fall into with "the grass is always greener", but let's not make Andy Dalton out to be some sort of Heaven-sent savior.
