Allen has the clutch gene but to be clutch requires confidence. Mahomes has the clutch gene and when he pulls off a magic trick he’s rewarded with wins. Allen, on the other hand, ends up with some success, some mind numbing drops, and an occasional miss. For a QB to be clutch it requires himself and another most of the time to pull it off. Where they differ is as time has passed Allen has lost some faith in pulling off miracles whereas Mahomes is fully confident in the ability to do so.
