But here is a breakdown of several key Steelers who will see their first action on the NFL's biggest stage:
Analysis: Known in Pittsburgh as the "Young Money Crew," Wallace, Sanders and Brown have stepped up huge for the Steelers. Wallace is an elite deep threat and has carried the Steelers' passing game this year. Sanders has come on as a legit No. 3 receiver, while Brown has made his mark in the playoffs with back-to-back big catches to end games. This trio needs to step up for Pittsburgh to win its seventh championship.
Analysis: Both running backs are playing in their first Super Bowl but under different circumstances. Mendenhall was on the roster in 2008 but broke his shoulder as a rookie early and missed the playoff run. Now Mendenhall is playing well in his first postseason. Redman has earned his way on the active roster this season after impressing the coaching staff while on the practice squad.
Analysis: It was questionable if Legursky would make the team out of training camp. Now the backup center is starting in the biggest game of the season. Pro Bowl center Maurkice Pouncey suffered a high ankle sprain in the AFC title game against the New York Jets. Legursky filled in admirably for more than three quarters and also had two full weeks to prepare.
DE Ziggy Hood
Analysis: Hood is another injury replacement. He filled in for Aaron Smith (triceps) most of this season and played well. Pittsburgh still led the NFL in run defense and the Steelers finished second in total defense, despite Smith's injury. Hood also is playing his best football in the playoffs.
Analysis: Although one of Pittsburgh's oldest players, Adams, 35, has zero Super Bowl experience as a longtime member of the Dallas Cowboys. The Steelers have taken the approach all week to "win one for Flozell." Not only does Adams have a chance to win his first ring, but he can do it in the same city he played most of his career.
