Retired running back Tiki Barber, debuted as an analyst for NBC's Sunday Night Football by ripping Eli Manning's ability to lead the team. Manning shot back on Tuesday. "I guess I'm just happy for Tiki that he's making a smooth transition into the media world. It'll be interesting to see if he has anything else to say (about anything) besides the Giants and what his comments will be on that. It's one of those deals; I'm not going to lose any sleep (over) what Tiki has to say. I guess I could have questioned his leadership skills last year with calling out the coach and having articles about him retiring in the middle of the season and (how) he's lost the heart. As a quarterback, you're reading your running back has lost the heart to play the game and it's about the 10th week. Well, I could see that a little bit at times. But I'm not going to get concerned and I'm going to go out there and play ball. "It's just one of those deals. The guy goes to the media and he's got to say stuff. He's been put in a situation where he's got to talk. That's just the way it is. That's the world we live in and you have to deal with it."
