I know I see through my blue tinted glasses, but I think a reason Kansas's flames out of the NCAA tournament most years to teams seeded lower than them is they get so many calls from officials in the Big 12 home & away, they do not know how to adjust when the calls aren't going their way.
Kentucky on the other hand, it is questionable that we get many calls at home, as our opponent has shoot more free throws than we have. When we go on the road we get no calls, while this may hurt us during the season come tournament time our players know how to play when you are not getting any calls.
I don't believe this is the case at all.
It just happens. Teams get upset. Sometimes the best team doesn't always win
Last season they lost to Wichita St. That's a team IIRC has been wanting to play Kansas in the regular season for years and have been denied. I'm sure that played into it.
2014 - 2 seed lost in the 2nd round to Stanford (10) by 3 points
2013 - 1 seed and lost to Michigan in the Regional Semis (4) by 2 points
2012 - 2 seed and lost in the title game. So this year they did better than expected based on seeding.
2011 - 1 seed and lost in the Regional Finals to VCU (11)......by 10
2010 - 1 seed and lost in the second round to Northern Iowa by 2
2009 - 3 seed and lost to Mchigan St (2) in the regional semis......so they did as expected.
2008 - 1 seed and won the title........so as expected or better
2007 - 1 seed and lost in the regional final to UCLA (2) by 13......slightly worse than expected
2006 - 4 seed and lost first round to Bradley (13) by 3
2005 - 3 seed and lost first round to Bucknell (14) by 1
Clearly KU has underperformed in the tournament. The massive fails came in 05,06,10,14 and 15. But the games have been so close I really don't think it has anything to do with officials from in the Big 12.
