is there a descriptor you can give the Eagles here? Are they underdogs, are they the obvious second best, etc?

While you might be in charge of the buffalo chicken dip or chicken wings during football season, here's a fun fact to you can also bring to your watch party: Louisville once had a team in the National Football League (NFL).

The Louisville Brecks competed in the NFL for three seasons, from 1921 to 1923. Here's some quick facts:

The Brecks played their home games at Eclipse Park until it burned down after a game in 1922. They then moved to Parkway Field.
Officially named the Louisville Breckenridge Football Club, the team was originally known as the "Floyds and Brecks," taking the name from an intersection near where they played.
The Brecks' schedule frequently featured NFL games, plus games against non-league opponents. They only won one NFL game in their three years, a 13-6 victory over the Evansville Crimson Giants in November 1922.

When the Brecks joined the league, the franchise fee was a mere $25 — that's ~$415 in today's money. Compare that to the estimated value of the two teams taking part in Sunday's big game, according to CNBC:

Philadelphia Eagles: $7 billion
Kansas City Chiefs: $6.07 billion

The Brecks left the NFL after the 1923 season to join a local amateur league known as the Falls City Football Federation. The team folded after the 1924 season.

There was also a second "Louisville" team in the NFL. The Louisville Colonels competed in the 1926 NFL season, but never played a home game — the organization was based in Chicago and created as a "road team" to help fill out the schedules of the league's other teams.
