Passionate or unbalanced? Endearing or annoying? It’s hard to be neutral on the two fan bases bound for New Orleans and Super Bowl LIX.

The big game brings together highly polarizing bands of rabid football rooters. There’s the Kansas City Chiefs’ crowd — Chiefs Nation as they like to call themselves — full of midwestern folksiness that frankly has a fading charm after their team’s fifth trip to the Super Bowl the past six years.

On the other side there are Eagles fans, who are probably happy to tell you they don’t need any @%&^*! nickname. If you must insist, “Gang Green” is probably as fittingly unsavory as this bunch would like a nickname to be.

Make no mistake, though. These are two deeply loyal fan bases that have stuck with their teams through some mighty lean times.

Between winning Super Bowl IV in New Orleans in 1970 and the first of the Chiefs’ remarkable nine straight division titles in 2016, Kansas City suffered through a total of 23 losing or non-winning seasons and overall went 50 years without another Super Bowl victory. After winning the 1960 NFL title, the Eagles didn’t win another championship until beating New England in Super Bowl LII seven years ago. That included a 27-10 loss in New Orleans to the then Oakland Raiders in Super Bowl XV.

So while their franchises are in full tilt dynasty-building mode, their fans all know it can get snatched away very quickly with no guarantee of return. Perhaps that’s why they go to great lengths to help their teams in all sorts of superstitious ways.

Several readers told the Kansas City Star that they burn Patrick Mahomes-scented candles from a local candle maker while watching the Chiefs play on TV (I’ll leave it to your imagination what Mahomes smells like as a candle). One reader said his wife will light a second “Home Sweet Mahomes” candle if the Chiefs get into trouble.

“It works … most of the time,” Roger Viola told The Star. “So how can you not believe in it?” How indeed.

Stacy Williams, a bartender at a Philadelphia area watering hole, told the Cherry Hill (New Jersey) Courier Post that she knows of an Eagles fan who hasn’t washed his DeVonta Smith jersey since last year, though I’m not sure that would make the Amite native want to visit that bar. “Another (fan) told me he has to say ‘Go Birds’ 15 minutes before getting out of bed,” Williams said.

Quirky habits of Chiefs and Eagles fans get thrust into the shadows by the wattage of star power from these teams’ famous fans.

Of course, there is the queen Chief fan herself, Taylor Swift, the superstar singer who is dating Kansas City tight end Travis Kelce. But she’s hardly the only big name in Chiefs Nation.

There’s actor Brad Pitt, who grew up in Springfield, Missouri, and actors Jason Sudeikis (Ted Lasso) and Paul Rudd, who went to the same suburban KC high school (Shawnee Mission West on the Kansas side). Henry “The Fonz” Winkler is also a Chiefs fan. The Nation has gone international with the addition of “Superman” actor Henry Cavill from England (Smallville is in Kansas, after all) and Vancouver, Canada, singer Michael Buble, who got hooked on the Chiefs by his friend, former “Modern Family” star and Kansas City native Eric Stonestreet.

In the Eagles’ nest are President Joe Biden who is from nearby Scranton, Pennsylvania, but now calls even more nearby Delaware home. There’s singer Pink, a surburban Philly kid, as is actor Bradley Cooper. Actor Will Smith even sang the true to life line in the “Fresh Prince of Bel-Air” theme song, “In West Philadelphia born and raised …” Philly native Dawn Staley often coaches her South Carolina women’s basketball team in an Eagles jersey, and actor Kevin Hart is as dedicated to his hometown Eagles as anyone.

“Everybody knows I eat, sleep and breathe green,” Hart said.

Native American activists have criticized Kansas City for its nickname and the habit of fans to do a tomahawk chop at home games. Eagles fans, who once threw snowballs at a guy dressed as Santa Claus during a halftime promotion (in fairness, Philadelphia was 2-11 at the time) have been pleaded with by New Orleans city officials not to climb the city’s aged light poles and traffic signals if their Eagles win the Super Bowl, as they do back in Philly.

Just as sure as we’re going to see a State Farm commercial with Mahomes or that Fox will train its cameras on Swift cheering on her boyfriend during the game — can we call Vegas to put a prop bet on which gets shown more Sunday? — we’re sure that we haven’t seen the last of Chiefs Nation or Eagles whatever they call themselves at the Super Bowl.

Get ready, San Francisco Bay area. The red and green could be coming your way next year for Super Bowl LX.
