The victory, which moves the Patriots into a share of the all-time mark with the Pittsburgh Steelers, was also a record sixth Super Bowl triumph for Tom Brady, who at 41 became the oldest quarterback to win the championship game.
Brady was joined in the record books by 66-year-old Bill Belichick who becomes the oldest coach to hoist the Vince Lombardi trophy.
Brady again orchestrated the victory finally cracking open a tight 3-3 defensive battle late in the fourth quarter when he hit Rob Gronkowski with a 29-yard pass to set up a two-yard touchdown run by Sony Michel.
The Rams looked ready to hit right back when Jared Goff marched Los Angeles into New England territory only to be intercepted on the four-yard line with four minutes to play.
Brady moved in for the kill with another drive to set up kicker Stephen Gostkowski who nailed a 41-yarder with 72 seconds remaining to clinch New England’s third Super Bowl since 2015.
