Framed jerseys line the perimeter of Von Miller’s expansive basement. The walls are a who’s who of the NFL’s elite from yesterday and today: Drew Brees, Champ Bailey, A.J. Green… Twenty-four players have bequeathed a game-worn jersey to the affable Denver Broncos linebacker, who approaches his peers postgame, Sharpie in hand.

“You the best in the biz!” writes Dolphins quarterback Ryan Tannehill.

“Will never forget playing flag football in the middle of Afghanistan with you and all the soldiers,” writes Texans defensive end J.J. Watt.

Reading the jerseys feels like peeking at the back pages of Miller’s yearbook, but they’re just the beginning of what makes this basement something to behold. It is a magnificent man cave—basically a football fan’s Mecca—and the Broncos’ refuge.

“Club 58,” as his teammates call it, puts real clubs to shame. It has eight massive TVs, three arcade game systems, a 300-gallon saltwater fish tank, a pool table, and dozens upon dozens of top-shelf liquors, which are neatly organized behind a pristine, white-marble-countertop bar. The nine leather stools that surround the bar are extra wide—an amenity for Denver’s linemen.

Miller designed the basement for his boys.

“In football, camaraderie, the spirit of the corps, and just that bonding you need to be great—it’s essential,” says Miller.

The Broncos relax in Club 58 after Sunday home games until the wee hours of Monday morning. Following Denver’s triumph over the Patriots in the 2015 AFC Championship, more than 200 guests flooded into the basement, celebrating until 8 a.m. Cars were parked all the way down Miller’s street, which is located in a quiet Denver suburb near the team’s practice facility.
