"I still feel like today, if I wanted to come back to football and play football, I could do it, at the age of 55," Rice said during an interview for ESPN The Magazine's Body Issue. "I'm one of those guys that I still believe that if I wanted to, I could come back, catch over 80 balls and really be productive on the field. ... I think I'm still explosive, and I think I still can beat up on some defenses."
Rice, who is considered to be the greatest receiver to play the game, is the NFL's all-time leader in receptions (1,549), receiving yards (22,895), all-purpose yards (23,546), and touchdown catches (197).
He was in attendance during a 49ers training camp practice last August and even showed he could still run routes with the younger receivers on the team.
"I went out and I practiced with the [49ers] football team last year," Rice said. "The young guys could not believe that after playing a game for 20 years, and being out of the game for 15 years or something, my body knew what to do -- that I could run routes, that I could catch the ball, that I can beat them off the line of scrimmage and do all those things. I think that really impressed them. But because I never got out of shape, my body just knew what to do the second I put on those football shoes."
