San Diego Fleet quarterback Philip Nelson somehow completed a no-look pass against the Atlanta Legends, blindly tossing the ball over his shoulder while he was being taken down.
Nelson's miracle inspired Mahomes, likely to the dismay of NFL defenses.
Nelson's throw was reminiscent of Mahomes' most famous play during his 2018 MVP campaign.
Chiefs receiver Sammy Watkins said in January that the young passer tries even wilder throws during practice.
With Nelson raising the bar for absurd passes, Mahomes might be tempted to put his practice tricks to the test.
