He was selected to three Pro Bowl teams from 2000, 2001, and 2002, and is currently ranked sixth in Steelers all-time career sacks with 77.
[2] Gildon played a large role on the Steelers special teams unit during his first two years before being inserted into the starting lineup in 1996, after All-Pro pass-rusher Greg Lloyd, Sr. went down in the season opener with a torn knee ligament.
Gildon was most remembered in 1997 for recovering a Drew Bledsoe fumble late into the Steelers 1997 Divisional Playoff match-up against the New England Patriots; the Steelers would win this game 7-6 thanks to Gildon securing the ball, preventing a possible Patriots field goal or touchdown.
He was named to his second Pro-Bowl, but his dreams and that of the Steelers' of getting to the Super Bowl were erased after a defeat to the Patriots in the 2001 AFC Championship Game.
Midway through the 2004 season, the Jacksonville Jaguars signed Gildon to their roster, who needed help at defensive end.
In Feb. 2015, he beat out 40 applicants from 10 states and became the head football coach at Cardinal Wuerl North Catholic HS in a Pittsburgh suburb.
