I have no doubt that it is the goal to have the Pac-12 #2 team in Las Vegas, but it can't just happen, I'm guessing there are contracts that need to expire first.
Honestly, the Holiday Bowl should swallow their pride and move to Sofi. With the Rose Bowl happening close by, I don't think we'll ever see So-fi in the mix to host the CFP, but who knows, times are a changin.
The whole lack of good stadiums out west was/is such the fault of California. This is why our #2 team goes to San Antonio. Took the beloved 49ers forever, Raiders couldn't get on there, Chargers couldn't get one there. It's pretty sad how that all went down. If San Diego had a nice new stadium that woulda improved the Holiday Bowl, but nah.
