It's the flash and sizzle of Miami as a city and isn't just relegated to the Canes—although "The U" started that hate in the '80s.
College football was the slow Big Ten, the slow Big 8, the soft Pac-10, the forgettable ACC, the not-what-it-became SEC, the useless MAC, WAC, etc. and then Miami rolling in as an Independent and laying waste to the sports as people knew it.
If you grew up in the Midwest, the South, the Northeast—you grew up hating a Canes program that probably kicked your team's *** somewhere along the way.
Imagine what Colorado tried to be this year with attitude and swagger—and then imagine them winning 58 games in a row at home, four titles in nine years (while leaving a few on the field) and having an NFL brotherhood and fraternity that other players and fans were envious of.
Go back and watch "The U" and The U Part 2"—there is NO college program like Miami, nor is there a sports city that has all the glitz and glam that South Florida has. Only thing that rivaled it was the Jerry Buss '80s era Lakers and Los Angeles for that time period—except Miami has the Canes, the Heat, the Panthers, the Marlins and now Inter Miami CF... plus night life, South Beach, great weather, miles of beaches, the Florida Keys, Coconut Grove, etc.
Most sports fans—college and pro—live in miserable cities with miserable weather and a slew of fat, miserable overweight fans who have to suffer through the four seasons and a grind of an existence—where there respective teams are everything.
You think average Americans wanted to see the flashy Miami Heat make it to the NBA Finals? There's a reason everyone became a Milwaukee fan, a New York fan, a Boston fan and a Denver fan.
If that is ANY other eighth-seed that played into The Finals going against the top seeds—please—it's hands-across-America for the underdog and everybody is pulling or Cinderella to land the upset.
The City of Miami is the villain; the Hurricanes a large piece of that—disliked while they suck, but supremely loathed the minute they get back on top again.
Nature of the beast and always will be as this hate started decades ago and will never stop.
