Sirianni is in his second year as Philly's head coach, and they have dominated the NFL postseason thus far.

Earning a first-round bye with their 14-3 record, they have outscored their opponents 69-14 so far - they beat the New York Giants, 38-7, and then the San Francisco 49ers in the NFC Championship, 31-7.

Sirianni wasn't a finalist for head coach of the year, but he received six first-place votes.

It's the Eagles' first trip to the Super Bowl since winning back in 2018, taking down the New England Patriots in Super Bowl LII.

EAGLES' NICK SIRIANNI ON WHAT HE TOLD HIS TEAM AHEAD OF SUPER BOWL LVII

Sirianni didn't exactly receive the benefit of the doubt when he was initially hired - he had a rather cringeworthy introductory press conference, and plenty throughout the league continue to criticize his antics.

However, he has proven he can be a leader of men all the way to the final game of the season.

Sirianni earned his first head coaching gig in 2021 when the Eagles hired him after being the Indianapolis Colts' offensive coordinator for the previous three seasons.
