Marcus Cannon was a powerful, versatile TCU tackle — but he is now a former player
Marcus Cannon was an NFL-caliber run blocker and a durable, versatile offensive lineman at TCU and beyond, with the size, power, and tackle/guard flexibility teams covet; he earned a place in the TCU Athletics Hall of Fame after helping fuel a 25-1 run in his final two college seasons, and his pro career was shaped by resilience after a serious lymphoma diagnosis early in his career. For a team, he fit as a high-floor, physical lineman who brought toughness and positional value, but he is not a current TCU athlete because he retired from football after an 11-year NFL career.
