under Bronco?

Top 5:
1) Oklahoma 2009 (beat #3 on the road, big national audience)
2) TCU 2006 (beat #15 by 2 scores on the road, completely redefined the rest of the season)
3) Oregon 2006 (Solid victory of a trash talking PAC 10 team who "didn't want to be there")
4) Texas 2014 (Proved that 2013 wasn't a fluke, demolished them on the road)
5) UCLA 2008 (One of the most solid butt kickings of a P5 team I've seen)

Honorable mention:
Utah 2006, UCLA 2007 part II, Utah 2009, Oregon State 2009, SDSU in 2012 (just for KVN), Texas 2013

Bottom 5:
1) FSU 2009 (We were top 10, but got destroyed by an unranked team at home)
2) Utah 2011 (54-10. 'nuff said).
3) Utah State 2014
4) TCU 2009 (Clawed back into rankings after FSU debacle, homecoming, and ESPN Game Day)
5) TCU 2008 (Ranked #8, had a 16 game winning streak dashed)

Dishonorable mention:
Tulsa 2007, Utah State 2010, SJSU 2012, Virginia 2013
