Dawson played center and guard at Kentucky. He lettered in each of his four years. In his freshman year in 1984 the team defeated Wisconsin in the Hall of Fame Bowl. As a senior in 1987 Dawson was named second-team All-Southeastern Conference.
Professional career
Dawson was selected by the Pittsburgh Steelers in the second round of the 1988 NFL Draft. In his rookie season he played guard alongside Hall of Fame center Mike Webster. When Webster left the team following that season, Dawson succeeded him as the starting center. He soon became one of the more respected players among the Steelers, and one of the best in the league at his position. He earned the name "Dirt" for the way he would try to grind defenders into the ground. In contrast, his friendly off-field demeanor led to a second nickname, Ned Flanders, after the annoyingly cheerful character from The Simpsons. Dawson was named to seven straight Pro Bowls from 1992 to 1998 and was a six-time AP First Team All-Pro. In 1993, he was named co-AFC Offensive Lineman of the Year by the NFLPA and in 1996 he was named the NFL Alumni's Offensive Lineman of the Year. He played in 170 consecutive games, the second most in Steelers history, until severe hamstring injuries forced him to sit out nine games in 1999 and seven more games in 2000. Dawson was released by the Steelers following the 2000 season partly due to these injuries and partly due to salary cap reasons. He opted to retire rather than trying to play for another team. He is the only player to have played in the two most lopsided games in the Browns–Steelers rivalry, getting his first career start at center in the Steelers 51-0 loss to the Cleveland Browns at home, but was victorious in the Steelers 43-0 win against the Browns in Cleveland ten years later, in the Browns' first game in four years.
Dawson was named the first-team center on the National Football League 1990s All-Decade Team. In 2007, he was selected for the Pittsburgh Steelers All-Time Team which was named as part of the franchise's 75th season celebration. Although the Steelers no longer officially retire uniform numbers, the number 63 that Dawson wore has not been reassigned since his retirement. He was elected to the Pro Football Hall of Fame in 2012 following three straight years in which he was a finalist for the distinction. In 2001 Dawson and his wife established the Dermontti F. and Regina M. Dawson Endowed Graduate Fellowship in Education scholarship at his alma mater, the University of Kentucky. Dawson was appointed to the school's board of trustees by Kentucky governor Ernie Fletcher in 2005. He is a member of UK's College of Education's "Alumni Hall of Fame" and the UK Hall of Distinguished Alumni as well as a charter member of the UK Athletics Hall of Fame. In addition, his jersey has been retired by the school.
