American football rules
Super Bowl LI was the first Super Bowl to go into overtime with a 28-all tie between the Atlanta Falcons and New England Patriots, which the Patriots eventually won with James White scoring a touchdown on the Patriots' first drive.
History of the Pittsburgh Steelers
Zereoue, filling in for Bettis, scored two touchdowns in the divisional playoff against the defending Super Bowl champion Baltimore Ravens, which the Steelers won 27–10. Pittsburgh then hosted its fourth AFC championship game in eight years, this one against the New England Patriots. Optimism was high as Bettis made his return. The Patriots jumped out to a big lead thanks to two special teams touchdowns, but the Steelers tried a third-quarter comeback with rushing touchdowns by Bettis and Zereoue. Kordell Stewart's final two drives both ended in interceptions, however, and the eventual Super Bowl champion Patriots won the game 24–17.
