Personally I think Mayfield sucks, and changing from OBJ and Landry, with Chubb at RB to Beasley, Brown, great for eight carries Singletary at RB, mayfield would suck worse. .
Darnold would not have more wins, because he would have had mono. Darnold is the 2018 QB with the turnover problem, so he would have fewer wins. Hard to say with Jackson. I Buffalo he probably would be sitting the bench behind some peterman clone because Daboll would have no idea what to do with him. But if the entire ravens offense and coaching staff came over, we would definitely score more points and win more games.
