Big 12 history: 15 seasons, and dominant early, with conference titles in 1997 and 1999, but none since. Six division titles, including 1996, 2006, 2009 and 2010; 81-39 conference record.
Final Big 12 seasons: Some momentum, with North Division titles their last two seasons, with tight championship game defeats to Texas (13-12 in '09) and OU (23-20 in '10).
Big Ten performance: One division title (2011) in three seasons, with an overall conference record of 17-7.
Big Ten outlook: Huskers came out good in Big Ten divisional realignment — the west division does not include Ohio State, Michigan, Michigan State and Penn State. Wisconsin, Iowa and Northwestern figure to be Nebraska's chief opposition.
Big 12 history: 15 seasons, one championship (2001), three other North Division titles, 60-60 conference record.
Final Big 12 seasons: Hard times. CU went 2-6 four of its last five seasons in the Big 12 and had a winning conference record just once (5-3 in 2005) in its final eight years in the league.
Pac-12 performance: Dismal. The Buffs have gone 2-7, 1-8 and 1-8 in its three Pac-12 seasons.
Pac-12 outlook: Dismal. The Buffs are in a division with Southern Cal, UCLA, Arizona State, Arizona and Utah. The arrow is pointing up on most of those programs. Who can Colorado jump?
