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.
Adam Vinatieri
In 1996, Vinatieri was signed by the Patriots as an undrafted free agent to be a placekicker. He played in New England for the first 10 years of his NFL career, during which he played in four Super Bowls, winning three titles. In his rookie season, he chased down and tackled Dallas Cowboys returner Herschel Walker on a kickoff, leading then-Patriots head coach Bill Parcells to tell his rookie kicker "You're not a kicker—you're a football player." His first Super Bowl appearance was in his rookie season of 1996, when he played with the Patriots in their 35–21 loss to the Green Bay Packers in Super Bowl XXXI. One of his kickoffs in the Super Bowl was returned by Desmond Howard for a Super Bowl-record 99 yards and a touchdown that ended the Patriots' bid for a comeback.
