Kelly Michael Gregg (born November 1, 1976) is an American radio personality and a former professional football nose tackle.

He spent time in his early career with the Cincinnati Bengals and Philadelphia Eagles, and was a starter for the Kansas City Chiefs in 2011.

His nickname Buddy Lee was coined by Tony Siragusa when they first met on the day Gregg signed with the Ravens in September 2000.

[4] In football, he was a two-time All-State selection and was named the city's Defensive Player of the Year by the Daily Oklahoman as a senior in 1994.

Named All-Big 12 first-team as a Junior (1997) and Senior (1998), despite playing for teams with losing records in both seasons.

Over the following years, he helped maintain the Baltimore Ravens' reputation as a team with a top notch defense.

He was a key part of several multi-game stretches of time where the Ravens defense did not allow a 100-yard rusher in a single game.

Gregg was placed on season-ending injured reserve on October 8, 2008, after he underwent microfracture surgery on his left knee.

[9] While never voted to a Pro Bowl in his ten years as a Baltimore Raven, he was often considered one of the most effective nose tackles—and one of the most underrated players—in the league.
