2. Mike Webster: 220 games played with Steelers
Now we are starting to get into some uncharted territory when it comes to longevity with the Pittsburgh Steelers. Despite starting his career in the early '70s, Mike Webster was able to stick around as the starting center in the NFL all the way until 1990 (though his final year with the Steelers came in 1988).
Webster's outstanding NFL career consisted of five First-Team All-Pro honors and 9 Pro Bowl appearances. These were well-deserved, as Webster was one of the best to ever play his position in the NFL.
In terms of longevity, Webster outlasted Hall of Fame quarterback Terry Bradshaw. Heck, by the time he hung up his cleats, he was only five years away from seeing the Kordell Stewart era begin. Webster had two seasons cut short due to injuries -- suiting up for just 9 games in 1982 and in his final season in 1990. It's also worth noting that the NFL didn't move to a 16-game schedule until Webster's fifth season, so he could have had even more games under his belt.
It's exceptionally rare to find a player at any position who could play this many games in the NFL. Even though he played his final two seasons in Kansas City, he still finished second on this list with 220 games played in his Pittsburgh Steelers career (245 total in his career).
