Several things of note:
Not every player actually played in all those playoff games, but they did dress and were considered active. I’m not sure this entirely matters, though. It’s probably very important for young players to get to see a playoff game and experience the atmosphere and intensity of the event. I’m sure it’s better to actually play, but just being there is next best. DT Scott Paxon is the only player who has no playoff experience who is not a rookie. Our 2003/2004 draft classes are boss, with several stars still here with tons of playoff experience.

26 players have 4+ playoff games under their belts, with 18 having atleast 1 game, and only 8 players having none. The average number of playoff games per player is 4.3 games! This is unbelievable. This has got to be the most playoff-experienced team in the NFL. Also most players have some experience playing for the Steelers in the playoff, which comes with massive pressure from fans' expectations and a demand of excellency from the franchise itself. Something else of note: The Pittsburgh Steelers have been in 11 playoff games in the past 7 seasons (not including this season, yet) and they have won 7 and lost 4. Unbelievable. Can you imagine the joy of, say, a Detriot Lions fan if his franchise has those stats. I love the consistency of this franchise. They really do things the right way. Finally, James Farrior is a beast, ‘nuff said.
