Tiki Barber admits there was more than one day during his retirement when he would wake up, have coffee and breakfast and then "sit on the couch and do nothing for 10 hours." "I started to shrivel. I didn't have that confidence. I didn't have that aura anymore," Barber said in an interview. In the HBO piece, billed as "Tiki Barber's first extended TV interview since his comeback announcement," Barber explains why at the age of 36 he has turned back to football four years after retiring from the Giants. "The game never needs you because there's always someone else to come and take your place," Barber said. “But right now, I need the game. I need to prove to myself that I can be successful at something. I know I'm going to be successful as a football player. I don't know why. The odds say 'No.' I'm 36 and I haven't played in four years. But I just know."
