From a very small sample size , I feel Darnold has a high floor but low ceiling compared to Baker and Allen at least.
We all heard he's the most pro ready QB and that's probably true but it's almost a double edged sword p because I don't forsee his game making any big time improvements that Allen / Mayfield ,specifically , are CAPABLE of making..
I see Darnold being a serviceable, game manager type of Q . You can win SBs with that type, but ur run game, ST and defense need to be elite.
Allen def has a lower floor but no question his ceiling is much higher and as a Bills fan and the QBs we've witnessed since Kelly , that's music to my ears. Roll the dice.
