I think Baker was a terrible fit for Stefanski. Stefanski likes guys who can keep the train on the tracks and that simply isn't Baker. Sure, Baker might scramble around sometimes and make a big play, but 80% of the game, he won't execute it exactly the way you want it.
Whereas Brissett is in the NFL because he's a big, physical, and knows how to run an offense. Similar to when Stefanski had Keenum as his QB, but I do think Brissett was better than as advertised on here. He's good enough to make the offense work.
Cooper has always been awesome, just got overshadowed by Lamb in Dallas, for whatever reason. He's fair and away better than Landry, but probably about on par with 2019 OBJ.
