Manning in 2009, before injuries sidelined the future Hall-of-Famer and upset his career.
If he were to become a Cardinal, Manning’s wings would be a cure for his below-average foot-speed and age-slowed athleticism. Plus, his feathers give him a nice red sheen.
Becoming a Dolphin would be a stellar way for Manning to deal with his neck issues, since dolphins don’t really have necks. Due to the flipper situation, arm strength and deep throws could be a problem, but he’d instantly be a far more mobile quarterback when under water.
Manning’s best chances of returning to pre-injury form would probably come as a Bronco, combining his unmatched football IQ with four legs and a healthy, powerful tail. And considering that the bulk of his career came as a Colt, growing into a full adult horse seems like a natural next step.
It’s too early to rule out Manning as a Titan, though. Being made of smoke and fire would do wonders for his durability, and Peyton’s size—6’5” as a human, incredibly insanely huge as a Titan—could once again become a strength.
