The network announced Wednesday that Simms will move to The NFL Today show as a studio analyst.
Simms spoke with Sports Illustrated's Richard Deitsch about the move Wednesday.
"Listen, I didn't make any comments for a lot of reasons and you want to sit there and think about it," Simms said. "Initially was my pride hurt? Absolutely. Of course it was ... So it took a little bit. Not long. I started thinking about it in a positive way and then I became excited about it.
"[CBS Sports Chairman] Sean [McManus] had talked to me over the years about maybe going into the studio. I now get to follow the league like I want to. That was probably the most frustrating thing about my job. You do one or two games a week, you can't really pay attention to the other teams like I wanted to do. When you do games, you are all-in on those games. On Inside The NFL, I get to say things about stuff that I never get to say in a broadcast."
Simms will replace Tony Gonzalez in the CBS studio, and will join James Brown, Bill Cowher, Bart Scott and Boomer Esiason.
The announcement comes two weeks after CBS signed Romo to replace Simms as the No. 1 game analyst. The ex-Dallas Cowboys quarterback usurping the lead role left Simms in temporary limbo.
Simms has been in broadcasting since retiring following the 1993 season. He had been CBS's top in-game analyst since pairing with Greg Gumble in 1998, following stints at NBC and ESPN.
