I don’t understand how Payton was able to adjust and do such solid work with Winston and even Teddy Bridgewater., but not really seem to learn much from that.
I get that he ultimately ended up as a career backup, but let's not pretend he was some undrafted or late round rando who happened to look impressive enough in preseason to make a team. He was a first round pick who ended up making a pro bowl and started a playoff game.
