Tiki Barber credits his girlfriend with motivating him to return to football, he told the New York Post.
Wyche: Barber's return won't be easy
"I went through and am going through a divorce, and as much as you want to put on a brave face, it gets hard," Barber told the Post on Wednesday. "There were times ... where I didn't even want to leave my house. I was literally sitting around doing nothing. I couldn't motivate myself to do anything.
Barber said Traci Johnson, a 24-year-old former NBC intern whom he met while working on "The Today Show," finally helped him snap out of his funk.
"When we first met, he was completely motivated. He wanted to have an influence on everything, wanted to make an impact," Johnson told the Post. "And so it was a complete shock just to see him basically disintegrate."
Barber admitted to having "made mistakes," though he didn't go into detail as to what those transgressions were. Barber's ex-wife reportedly was eight months pregnant when he was seen around New York with Johnson and subsequently slapped with divorce papers.
Barber retired following the 2006 season after 10 seasons with the Giants. He then was hired as a correspondent for the "The Today Show" and "Football Night in America."
Barber was fired from NBC in 2010.
After spending so much time indoors depressed, Barber said he's ready to get back to work -- outdoors, playing football.
Barber, according to USA Today, recently sent a text to his manager that read: "I'm on a mission of redemption."
