Semis make it across country all the time, for games. ND goes to USC, noncon games across the country happen all the time.You going to fly two semi loads of football equipment each week too?
It's not just moving teams to new game locations we are talking about here.
One thing about the semis, they can leave anytime during the week. Its not like the players, Semis can leave on Monday if they need to, to be there on Friday/Saturday.
This is nothing new. And it is not like USC is going to play Maryland every week, they will be lucky to play them every few years. Just like we wont play UCF every year. No matter what system they go with, divisions, pods, rivalries, your nearest are going to be your regular opponents, and the far away teams will be played every few years, depending on the rotation.
Right now USCLA are on an island. But that doesnt mean they wont add a couple more regionals. WVU has been on an Island in the Big12 for years. But now even though the Big 12 footprint has expanded, a team like WVUs travel will actually go down.
