This is going to sound bad, I don't mean to sound bad, but...
I'm not a conference rah-rah guy. Obviously I'm glad your teams won as much as they did because they're your teams and you're good dudes (dudettes?), but not because they're in the ACC. Maybe it's because I'm a U of L fan and we've been through plenty of different conferences so I've learned not to care much. I'm really ecstatic that ACC teams won 20 games in the tourney, not because of GO ACC! but because we get more money. 20 tourney wins nets the conference as a whole, including U of L, a ton of bonus cash.
Same goes for football. Do I care what the ACC bowl record is at the end of the year? Do I care about Clemson's national title? Answer is no, I don't. I care that the ACC teams on our schedule win their regular season games, so if/when we beat them then that makes us look better. If Georgia Tech or Virginia Tech or Miami aren't on our schedule, do I care what they do during the season and in their bowl game? Not in the slightest. I don't hate them or anything and I don't actively root for anyone to lose, but in the end it doesn't move the needle much for me.
Maybe I'm just a horrible college sports fan...
There are teams I just won't root for, especially in the ACC.
Dook. I hate their rat (or ferret) faced coach, and anything to do with that miserable team. No amount of conference pride could ever bring me to root for those assholes.
Clemson. I can't stand them, in anything. Was happy to see them get kicked around by Kansas, even though I hate Kansas.
North Carolina. I don't like them, I don't root for them, but they're fairly benign....it's fun to watch them lose, though.
Florida State...I hate Michigan, and I root for chaos when it gets to later on in the tournament...so I was hoping the Noles would pull off an upset. I was hoping Loyola would beat them, so we could crown them "Florida State Champs" in 2018, after beating UM, UF, and FSU...normally I wouldn't root for the Noles, but this year I did, just wanting to see pure chaos unfold.
NCState...I could care less about them. They don't bother me. I always know they're going to lose in the first round, even if they have the more talented team...doesn't matter who the coach is, the song remains the same.
Syracuse...I don't mind them at all. I like Jim Boeheim...he's the Larry David of the college basketball world...so I didn't mind seeing them go on a run.
Virginia...I don't necessarily mind them, but I'm not a fan of theirs, either. I laughed my ass off watching them lose to the 16 seed.
Outside of the ACC, I actively root against many teams for a variety of reasons, including:
Gonzaga, Arizona, Michigan, BYU (though they weren't in it), Kansas, Florida, Oklahoma, Ohio State
But I also root for smaller schools, or mid-majors like: Wichita State, San Diego State, Houston.
Kentucky, a lot of people hate, but they don't bother me, either. I like Calipari. He's a boss....UCLA, too...though I think Alford is a loathsome loser asshole.
That's kind of my rooting guide once Miami's tournament went to hell.
