No offense to the OP, but I follow realignment pretty close and this link to a random website that is quoting some random dude on Twitter. Maybe it happens, but I highly doubt it.
I think it's more likely that the Stanford and Cals Hail Mary attempt to get into the ACC fails, and the PAC4 are forced to rebuild with select AAC and MWC teams over the next 2 years. Whether they backfill with the best of the rest from the AAC/MWC or just straight up merge with the AAC like the Twitter guy is saying, it just strengthens a G5 conference that we will have to compete with for a CFP spot.
With that said, I'm to the point where I no longer cheer for bad things to happen to other conferences. We don't need anyone else to fail for the SBC to succeed. It's up to all our programs in this conference keep elevating and raising the profile of the league. The SBC has certainly trending the right direction over the past few years.
