The difference is that Colorado, and the Arizona schools are not going to get an invite from the Big 10, and I doubt that Utah will either. The money they are getting right now is the worst amount the P5 conferences, and all four have to know that Oregon and Washington, and maybe even Stanford might get a Big 10 invite. So why show loyalty to the Pac 12, when the better schools will not?
The Big 12 does not need or want WSU, OSU, Boise St., SDSU or other schools. How many people were worried about what happened to ISU last year? Few if any, so why should we worry about those other schools now?
This is a KILL or BE KILLED deal, and schools like WSU and OSU are going to be left behind unless the Pac 12 stays together, but if they do, how long will that last?
