Golf, track, cross country are examples where schools don't play much of or any in-conference schedule all year long. They officially run the ACC Championship and that's it, potentially. I would think the killers will be baseball, softball, volleyball, basketball. Basketball is too much of a money maker so I'd think they schedule Cal/Stanford in for a two game long weekend...Sat to Mon/Tues. I'd think with baseball and softball, they will keep the teams out East for a two week trip...most classes have the ability to attend online, or they will make them available. They might deemphasize the full season for the west coast teams, it's the tournaments that matter. Let them play the west coast teams in baseball, softball, etc. So I could see travel being coast to coast travel and only occurring once a month.
I wouldn't be surprised if they use Atlanta/Tech for some mini-tournaments. You could play two or even three different teams in volleyball over one long weekend. Then hop back on the airplane with the cross country teams, etc.
The more I think about it or see ya'll's thoughts, the more I think it can be done and will work out a lot better than traveling every other weekend.
