Mora Jr., Weis, and Davie were just stupid hires in my opinion. For New Mexico though, I don't know who they could get. That's a dead end job.
Mora Jr. may turn out alright, but the history of that type of hire does not bode well for UCLA. Arkansas State couldn't do better than Malzahn.
By the way, you didn't include Memphis hiring Fuentes from TCU, and you didn't include Ohio State hiring Meyer.
ETA: I wouldn't say anyone made a slam dunk hire. Ohio State obviously made the biggest hire, but I have questions about Meyer after the way he left Florida. Leach is a good hire for Washington State, but I don't know that you'll see them overtake Oregon in the Pac-12 North. Nike money and Chip Kelly aren't going away anytime soon. That said, for a program that's been dead for years, Leach is a breath of life and will have them at the very least respectable. Plus he should be able to find plenty of accurate armed, under-valued 2 star QBs to recruit on the West Coast for his light up the scoreboard system.
