Tiki Barber, who will work on NBC's "Today Show" and on the network's Sunday night football coverage, said his problems with New York Giants head coach Tom Coughlin had "started to take its toll on me" and that it was an "act of God' that the physical demands Coughlin placed on him did not result in serious injuries. "Coach Coughlin is very hard-nosed, and I didn't get a lot of time off, couldn't sit down and rest myself, and so it was a constant grind -- a physical grind on me that started to take its toll," Barber told reporters Tuesday after his introduction as the newest correspondent of the "Today Show." "The grind took its toll on me and really forced me to start thinking about what I wanted to do next. And that's not a bad thing. That's a good thing, for me at least. Maybe not for the Giants, because they lose one of their great players, but for me, it is," Barber said. He spurned offers from Fox and ABC/Disney to take the NBC job. "My dream has always been to be on the 'Today Show,' " Barber said.
