GSP Says Justin Gaethje Should Retire: 'He's Already Achieved Everything'

Georges St-Pierre is publicly urging Justin Gaethje to walk away from the sport, telling the lightweight champion that his career has already reached its natural peak.

St-Pierre, the retired Canadian legend who compiled a 26-2 record across his welterweight and middleweight career, said he would choose retirement if he were standing in Gaethje's shoes. The 45-year-old, who trained out of Tristar Gym throughout his decorated run, framed the idea as a perfect conclusion rather than a criticism, questioning what more Gaethje realistically has left to prove.

Gaethje, 37, currently holds the lightweight title and carries a 28-5 record built almost entirely on forward pressure and violent exchanges. Fighting out of Genesis Training Center, the American stands five-foot-eleven with a 70-inch reach and lands an eye-catching 6.48 significant strikes per minute at 58 percent accuracy — numbers that reflect a style sustained by absorbing punishment as much as delivering it. His submission attempt rate sits at zero, and he averages just 0.33 takedowns per 15 minutes, meaning nearly every second of every fight plays out on the feet.

St-Pierre's own career offers an instructive contrast. The Canadian averaged 4.16 takedowns per 15 minutes and mixed grappling with striking at 53 percent accuracy across 28 professional bouts, retiring on his own terms with his legacy intact. That experience appears to be the lens through which he views Gaethje's current position.

Why it matters

• Gaethje is lightweight champion at 37, an age when the sport's wear begins compounding rapidly
• St-Pierre's comments add a prominent voice to conversations about fighter longevity and exit timing
• Gaethje's high-output, stand-and-trade style carries a physical cost that makes the retirement question particularly pointed
