IDK 31-33 overall NFL Record Coach of the Year in Atlanta and that's including only one year in Seattle where he was 5-11 on a bad team, but fired abruptly because Pete Carroll needed to get the hell out of Dodge before the violations hit USC and Paul Allen decided to go in that direction.
IMO, if Mora gets UCLA to a final four or a PAC 12 Title, he'll be on many short lists and he might want to give it just one more shot just like Pete Carroll. Now again this is only an opinion, but factor in a possible move to Los Angeles and you might have the perfect storm.
However, of the three you posted I would consider Hue Jackson 8-8 career record and a highly regarded assistant coach and I was upset when Fisher interviewed Jackson back 2012 (granted might have just been a courtesy) and went with Shottenheimer.
