Miami isn't garbage, but they're certainly not a top 10 team either. Probably more like 15-20, which is still good considering they were unranked to start the season.
This is nothing but good for the ACC though. Happens with teams from other conferences all the time. Thank God they pulled it out, that's the kind of game that's embarrassed the ACC every year.
If FSU beats Clemson, then that will be another mega-game for the ACC two weeks later when they host Miami. Possibly game day in Tallahassee, which would be the third visit to an ACC stadium in the season.
If FSU loses to Clemson, they'll have a decent chance to rehabilitate themselves with a drubbing of a top 10 team.
Or Miami could beat FSU and set up a huge showdown with a 1-loss VT game the very next week.
Overrated or not, it's perfect.
