The best quarterback in the world right now is probably Patrick Mahomes.

The two-time NFL MVP’s incredible passing skills have been a major factor in the Kansas City Chiefs’ two Super Bowl victories. With regularity, Mahomes completes passes that most quarterbacks would only dare to dream about.

In an episode of the Netflix documentary series “Quarterbacks,” Mahomes’ personal trainer Bobby Stroupe explained the “physiological” basis for the 27-year-old’s remarkable passing.

Since Mahomes’s early years as a Texan athlete, Stroupe, founder of the Athlete Performance Enhancement Center (APEC), has been by his side. After the Kansas City Chiefs drafted Patrick Mahomes in 2017, Mahomes, at the star quarterback’s desire, relocated to the city to serve as his full-time trainer.

According to Stroupe, a quarterback’s ability to make “off-platform” passes (such as sidearm slings, no-look passes, cross-body throws, and so on) depends heavily on the mobility of the quarterback’s neck and spine.

Some quarterbacks, according to Stroupe, can’t move their head while the ball is rolling to the right, while others can. Perhaps the same athlete can do it if they roll to the left.

He also noted that many quarterbacks suffer from weaknesses in both directions. And conversely, there are almost none with negligible or zero deficits.

Patrick, like an owl, “can keep his head perfectly still, like an owl,” Stroupe added, and he would still be able to see everything that was going on. And because of the flexibility in his spine, he can also manipulate his body.

Mahomes’ spine is strong and fast, and he is remarkably flexible on both sides of his body, such that when he swings a bat at full speed, there is little any loss of momentum as he rotates to the left or the right.

His hip-shoulder separation is “the best that I’ve seen,” according to Stroupe, who has worked with “some of the hardest throwers in baseball and at the quarterback position.”

Stroupe spends a lot of time working on developing Mahomes’ innate skills. They focus on his core by having him perform a wide range of twisting exercises with medicine balls, cable machines, and other apparatus in the gym.

Every Sunday (or Monday, or Thursday, depending on the week), Mahomes seems to reveal a new way to move and pass. And he and Stroupe are making steady progress toward that goal.

“How many different ways can you move to solve a problem?” is how I interpret “off-platform” throws. That’s what Stroupe claims.
