could have 2 losses....I'd say TCU/bu have the inside edge to finish with 1 loss.
bu 6-1 / 3-1 home vs ksu, road vs OU
ksu 6-1/4-0 road vs tcu, wv, bu
tcu 6-1 / 3-1 home vs ksu, at WV, ut
WV 6-2/ 4-1 home ksu, tcu road ut
OU 5-2 / 2-2 home bu, at isu (yes, ISU...the one that almost beat ksu and ut...trap game)
I'm assuming with any B12 team champion having 2 losses they are out of the playoffs....
