Could Michael Jordan play at 50? His trainer is ready if he does

 
As Tim Grover walked out of the Hall of Fame induction speech four years ago, the observances of Michael Jordan's old slights, the settling of old scores, had already come and gone in the trainer's mind. All those years with Jordan, and Grover understood to always be lurching toward tomorrow with the game's greatest player.

"I heard that speech differently than everybody else," Grover said. Grover heard Jordan raising the idea of playing in the NBA in his 50s, and that was all the nod he needed to begin preparations.
"If I ever get that call," Grover said, "I was going to be prepared for it. And I am." 

Fifty pages inside a binder sit on Grover's desk inside his suburban Chicago home now, information and studies and research and innovations into regenerating the muscle fibers and anti-aging advances and nutrition. From his trips to Europe and Asia and the Far East, Grover has incorporated a small library of intelligence – backed with the most intimate knowledge of Jordan's body and mind and drive – to create a program that awaits the comeback of all comebacks at 50 years old. 

Deep down, Grover isn't so sure that call will ever come, because the complications of owning the Bobcats could ultimately make a return too intrusive into Jordan's business life now. All these years later, Grover still makes sure he incorporates every morsel of cutting-edge information and technology into the binder, because if Jordan ever reaches out for the comeback of all comebacks, he needs to know one truth will have never changed with the passing of the years. "I'll be ready for him," Grover says. Yahoo Sports
