This is how I see each of those teams:

U of A = Above average PAC12 team that will be losing some key defenders but should still have their star QB returning. Just think that BYU matches up well with them. Bronco's teams do well on season openers. Perhaps a healthy Taysom Hill too....??

Utah = A very good team and (obvious) huge rival. Losing a bevy of key starters. But still think they will be too jacked to lose at home in this one. Bronco haters will be enraged in this one. Its a very winnable matchup for BYU, but just don't see it happening until 2017 in Provo.

UCLA = A very good PAC12 team. Loses some key starters on DEF (including Miles Jack, who actually declared pretty much after the BYU game this year). Rosen will be experienced and have a few games under his belt. I see these two teams evenly matched, but BYU has the edge in Provo - eeks out a close one.

WVU = An average team. Dana Holgersen could be losing his grip on that team by the time the game is played. WVU has historically had pretty good talent, but seem to be trending downward in recent years. They could hurt BYU with their speed, but I think BYU shows up in DC and makes a statement against a team we all feel leap-frogged BYU into the BIG 12.

Mich. St. = An elite team. Will be losing Connor Cook to the NFL, but will otherwise be able to reload and beat BYU at home. This is a team that typically plays very tough DEF and has very good RBs. Of all the potential wins, this is the least likely for BYU, IMO.

Miss. St. = A very good SEC team. Losing its All-World QB Dak Prescott will likely mean that offense takes a small step back. They have some big SEC boys and some SEC speed, but I think BYU can bring it and make some key stops/turnovers to win a close one at home. An experienced OL and the stable of RBs will help grind out first downs and keep the DEF on the sidelines during key stretches.
