Tom Nalen celebrating the Denver Broncos Super Bowl victory with head coach Mike Shanahan.
By linemen standards, Tom Nalen was a lean 287 pounds during his 15 seasons as a center for the Denver Broncos. With five Pro Bowl appearances and two Super Bowl rings along the way, Nalen had a nice career for a lowly 7th-round pick out of Boston College. But what he accomplished in his post-playing days might be even more impressive.
NFL weight: 287
Rookie year: 1994
Nalen had lost 72 pounds by the time he was inducted into the Broncos Ring of Fame.
After retiring in 2009, Nalen quickly dropped close to 75 pounds, getting his weight down to about 215 pounds. Nowadays, not even the Mile High faithful would recognize him without a name tag. In 2013, Nalen was named to the Broncos Ring of Fame (pictured above).
