I checked the bowl records since the 2004 football season and found the following to be very interesting:
Big XII - 39 wins; 35 losses (52.7%) - 14 wins; 15 losses last 4 yrs
Big 10 - 28 wins; 45 losses (38.3%) - 12 wins; 21 losses last 4 yrs
Head to head records - Big XII 15 wins; Big 10 6 wins
Bottom line is the Big 10 is always over rated so leaving the Big XII out of the final four in favor of another Big10 school should be no shock to anyone. I hope Baylor and TCU are fighting mad on game day.
There is so much missing from your comparison of Bowl W/L for ea. conference..
1) were the teams evenly matched, place in their conference, rankings
2) time off for ea. team
3) location - was it more or less a home game vs the opponent
Its not as easy as looking at the W/L..
