Pac-12 Football: The Split Personality Reigns Supreme

Only five weeks into the 2015 college football season and to quote Jerry Garcia of the Grateful Dead, "What a long, strange trip it's been!" In the preseason AP Top 25 poll, the Pac-12 had SIX teams in the Top 22 and a total of EIGHT which received votes.

Preseason:
# 7 -- Oregon
# 8 -- USC
#13 -- UCLA
#15 -- Arizona State
#21 -- Stanford
#22 -- Arizona

Two weeks in and things have changed. Arizona State lost to #27 Texas A&M, Stanford lost to Northwestern.

Week 2 Poll:
# 7 -- Oregon
# 8 -- USC
#13 --UCLA
#22 -- Arizona
#21 -- Utah

Stanford and Arizona State drop out of Top 25, Utah joins.

Oregon loses to then #5 Michigan State and drops in polls.

Week 3 Poll:
#  6 -- USC
#10 -- UCLA
#12 -- Oregon
#20 -- Arizona
#21 -- Utah

USC loses to Stanford, Stanford re-enters Top 25 but is still ranked behind USC.

Week 4 Poll:
# 9 -- UCLA
#13 -- Oregon
#16 -- Arizona
#18 -- Utah
#19 -- USC
#21 -- Stanford

Utah destroys and humiliates Oregon in Eugene, UCLA manhandles Arizona in Tucson, USC rips Arizona State. Undefeated California enters the poll and Oregon and Arizona drop out of Top 25.

Week 5 Poll:
# 7 -- UCLA
#10 -- Utah
#17 -- USC
#18 -- Stanford
#24 -- California

Arizona State dismantles UCLA in L.A.,  Stanford rips Arizona. Stanford finally is ranked ahead of USC

Week 6 Poll:
# 5 -- Utah
#16 -- Stanford
#17 -- USC
#20 -- UCLA
#23 -- California

After five weeks, Utah has jumped from unranked to #5. Oregon, Arizona State and Arizona have fallen out of the Top 25. Stanford has dropped out and then rejoined the Top 25. California is ranked for the first time in years.

The powerful Pac-12 has only two undefeated teams left... and that will change this weekend when Cal takes on Utah.

Only 3 teams are undefeated in conference play (Stanford, Cal and Utah) and that will drop to two after this weekend. Stanford has a bye.

---------------------------

Week by week, teams that played awful and lost the week before come back and upset a ranked team the next week. How it plays out is anybody's guess.

Will Dr. Jekyll show up and dominate? Or will Mr. Hyde ruin the day once again?
