20 Sports Legends Who’d Dominate With Today’s Science

Imagine handing modern sports science to the icons of the past. The protein shakes, cryotherapy, wearable trackers, hyperbaric chambers, and even those weird leg compression boots—what could some of the greatest athletes in history have done with all the tools we take for granted today?

Some of these legends already dominated with far less. Give them 2025-level recovery and performance gear, and they’d be unstoppable. Here are 20 sports legends who would thrive in today’s high-tech, health-obsessed era.

20. Wilt Chamberlain

When sports science was a good night’s sleep, Wilt put up video game numbers. With modern load management and recovery tools, he might’ve played forever.

Bo was a walking highlight reel whose body couldn’t keep up. Today’s injury prevention and recovery advancements might have saved us from what could have been.

Flo-Jo already looked futuristic when she was sprinting in the ’80s. With modern nutrition and training regimens, she might still hold records nobody could touch.

17. Mickey Mantle

The guy played through constant pain and partied harder than anyone should. Plug him into a modern training facility, and he’d be a different kind of monster.

16. Bill Walton

Walton’s feet betrayed his Hall of Fame potential. Today’s orthopedic care and performance tracking might’ve helped him dominate longer.

15. Eric Dickerson

Evert ruled the tennis court with mental toughness and relentless groundstrokes. Add strength training, hydration science, and modern analytics to her toolbox, and she’d be nearly untouchable.

13. Larry Bird

The first gymnast to earn a perfect 10 did it without techy mats, personalized recovery plans, or performance tracking. With today’s tech, her perfection might have lasted even longer.

Marino had the arm, the vision, and the swag—but no mobility. A modern nutrition plan and personalized training could’ve boosted his longevity and even landed him that elusive ring.

Sayers dazzled in a career far too short. Advanced medical care and load management might have kept him juking defenders for years.
