No, you made the mistake of comparing a player with poor accuracy to one of the most accurate passers of all time.
If you’re only making pro comparisons based on physical talent (dumb to do, especially with the QB position) then using HOFers to do so is just for a sensationalist response. Allen has as much a Dan Marino arm as he does a Pat Mahomes arm or a Mike Vick arm, but it just sounds crazier to say Marino. It’s even worse since you’re strictly comparing their arm strength but taking away something like accuracy. You’re not even comparing the players, just the one half of a physical attribute.
Like if I said my pro comparison for a guy is Randy Moss when it could easily be Stephen Hill.
