Or reading the room...
AD wants P5. Knows its only way to keep relevance in sport landscape. Those moves happen in next couple years. Only thing holding UNLV back is its major athletics programs particularly the future bellwether Football having success. You fire Arroyo because even though he mightve gotten you 6 or 7 wins next year thats not good enough. You hire a still young former SEC coach with 0 ties to the West and a bunch of hot coordinators (Petrino first, Marrion 2nd, and the DC thats going to be a riser, The experience of the remainder of staff) to take you past that- 9/10 wins year 1, maybe a MWC title, and then follow that up with a similar result and a title the following season. You sell 40k seats or better at Allegiant in year 2... Thats why this staff is here. They arent here to just get a to bowl game. Cant be afraid to hold the program to higher goals
