Warren was Third Round Pick from Auburn, and in his first seven years, he was on Special Teams and coming off the bench in pass-rushing situations. Warren finally became a starter in 1988, and in 1989 he had a 9.5 Sack year, his highest in Football. He could not build on that as he sat out the entirety of the 1990 season due to a year-long suspension due to substance abuse.
Warren came back with strong years in 1991 and 1992, and he played two more seasons before retiring in 1994.
Warren may not have been a Pro Bowler, but his tenure and pass-rushing skills earned him a rank on this list.
