New England Patriots head coach Bill Belichick is nothing short of legendary. And on Sunday night at Super Bowl LIII in Atlanta, he cemented his already stable legacy as the greatest coach in the history of football.

That may be a tough pill for some to swallow, but Belichick has now tied George Halas and Curly Lambeau for the most Super Bowl titles by a head coach (6), while his eight combined Super Bowl rings are the most of all-time. His nine appearances are also the most all-time by a head coach.

Additionally, Belichick surpassed former New York Giants leading man Tom Coughlin as the oldest head coach to ever win a Super Bowl title.

At 66 years and 293 days, Belichick stands alone atop of the NFL’s coaching Mount Rushmore. At the time of his Super Bowl XLVI title — ironically coming over Belichick’s Patriots — Coughlin was 65 years and 158 days old.

It’s no real surprise that Coughlin and Belichick are forever linked. Not only have two of Belichick’s three Super Bowl losses come against Coughlin’s Giants, but the two worked side-by-side under Bill Parcells from 1988-1990, defeating the Buffalo Bills in Super Bowl XXV as assistants.

Once a Giant, always a Giant.
