Willie Parker's longest run for the Steelers was an 80 yard touchdown. It was on December 24, 2005, against the Cleveland Browns.
The longest play you can make in the NFL is for a receiver in the end zone to run a kickoff back for a touchdown. A lot of players have done it.
I think it was Keith Byers in the 1993 snow Dallas/Miami Thanksgiving game.

Offensively, the longest play from scrimmage is the Pittsburgh Steelers "Fast" Willie Parkers 75 yard touchdown run in Super Bowl XL(40) against the Seattle Seahawks. Defensively, the longest play is the Pittsburgh Steelers James Harrisons 100 yard interception return for a touchdown in Super Bowl XXIII(43).
