Outside of Oregon and USC, this is a league Utah dominated last year to start. On top of that, most of the good talent in the league is gone so coaching becomes a huge factor.

Oregon lost most of their offense and 3 player opt outs
UW, new coach, new QB
USC as long as Helton is there, it's gonna be tough to call them anything other than uninspired
ASU, should be better, but Daniels needs to be a better passer for them to take a leap as a team

For as much as Utah is replacing, if Bentley is consistent, the schedule lines up nicely for them to go 5-1 and matchup against Oregon, Cal or UW for the title. I would say any one of 6 or 7 teams in the conference have a legit chance at the title game and winning the league including Utah. I also could see Utah losing to ASU, USC and UCLA if things don't go their way with a new QB. Arizona, Colorado and OSU are just not good programs right now and UCLA is a complete wild card.
