Gregg signed a one-year deal with the Kansas City Chiefs after the Ravens released him Thursday. The Ravens created $3.5 million in salary cap room by cutting Gregg, who had been the Ravens' starting nose tackle since 2002.
"I go back to the salary cap purge in Baltimore when we let Rob Burnett go," Gregg said. "We didn't think that would happen, but it did. It's a business. I have nothing to say but great things about the Ravens. They gave me an opportunity to play, and I had some great memories."
A practice squad player on the Ravens' 2000 Super Bowl team, Gregg survived the final cutdown in 2001 when he beat out Dwayne Missouri for one of the last roster spots.
Gregg moved into the starting lineup in 2002 after Tony Siragusa retired and Sam Adams was released. He became only the second Ravens defensive tackle to record 100 tackles in a season, and he did it four times (2003, 2005-2007). His 721 tackles rank second to Ray Lewis' 2,491 in Ravens history.
Gregg, 34, spent Saturday flying to Kansas City, Mo., which is close to his home in Oklahoma. He said the Ravens made an attempt to keep him. The Ravens will move Terrence Cody into Gregg's spot.
"They tried to re-sign me, but the chips landed in other places," Gregg said. "Actually, I feel like a rookie starting all over again. I trained very hard during the lockout because I didn't know when it was going to end, and I'm in shape and ready to play. I've got to get used to a new system, new teammates and a new routine. The last day has been whirlwind."
