The Kansas City Chiefs quarterback is just doing side quests at this point.

Patrick Mahomes has nothing left to prove to anyone. He may be chasing Tom Brady in terms of Super Bowl rings, but the 28-year-old has already carved out a legacy that not many other players in the history of the NFL can surpass.

He’s gotten to the pinnacle of the sport of football due to hard work, but more than anything because of his immense physical talent that pairs with his improvisational s𝓀𝒾𝓁𝓁s. It’s what makes him so dangerous when he leaves the pocket. And now, he’s showing he has another trick up his sleeve.
