I mean, I wish the entire sport would do this, but right now it would really make a ton of sense for the G5 to get together and sell their media rights as a package like the NFL. Pair off into geographically logical divisions (which would allow ALL sports to follow suit), and create some kind of season format where the G5 winner/best team plays in the 12 team playoff (you would still have early games against the larger schools).
They seem to be utterly cannibalizing each other at this point for absolutely no gain at all, and I don't think it's creating a more interesting product, whereas I think we are seeing (at least while the novelty of the new matchups is there) an even more compelling product in not just the Big 10 and SEC, but definitely in the Big 12 and possibly in the ACC too. But that's more a result of consolidation with (so far) very little shedding of schools in the aggregate. The G5 is splintering into smaller factions, which seems dilutive to me.
