Miami has always been hated. Difference was, it was 20 years of hating the Canes AND getting to laugh at 'The U' at the same time.
The media always (purposefully) fuels the "IS MIAMI BACK???" chatter early every season—whether it was that paper champ 7-0 squad that got wrecked at FSU in 2013, or Richt's merry bunch of overachievers in 2017—it's good business for the ESPN talking heads to build the Canes up, only to knock them down when they finally lose.
The media knows Miami is a polarizing program that is great to talk about, as there is so much national hatred for non-blue blood in the sport of college football—one that was a wrecking ball in the 80's, 90's and early 00's—and was that was always a talking point since, all the "What's wrong with The U???" segments.
Look at some of the most-viewed games in ESPN's history—Miami is usually on one side of it; Canes / Gators, Canes / Noles, Canes / Irish. A percentage of people watch to see Miami lose, while the rest tun in hoping the Canes lose.
It's like the Pig Vomit quandary in "Private Parts" as he can't fathom why people who hate him tune in and listen longer than fans; the same answer on both sides, "To see what he's going to say next".
People both love and hate 'The U' and play an active role whatever position they take.
