I think the Haslams got cold feet in 2012 about the loss of influence in the AD after negotiations with Coach Gruden. They made a last minute decision to bail (See Browns/McCarron as example)
Fast forward to 2017 and the Haslams already know what theyre going to have to give up in power pre-negotiation. They knew the writing was on the wall with Butch. They installed Currie behind everyones back to shore up their position against hiring Coach Gruden and his demands for control (see boosters vs. Bryant Jr. at Alabama). But Ergens side was ready this time. Curries approach to another coach may actually be an attempt to call Ergens bluff (see how serious he really is). Ergen, et al, is ready for just such a move and has a little help from a furry friend to gain support from the fan base. A little help from a venture capital firm to gain support from the Chancellor (see her decision to keep facilities management in-house). And, possibly, Peyton Manning with his rumored outside support for something???? Now, Mr. Haslam and Jr., are you on-board or not? (See once again Alabama vs. Bryant, Jr.).....
