I like to look at the out-of-conference games a conference plays (specifically the out-of-conference AWAY wins). Not that the Big10 is fantastic, but the Big12 is terrible.
OOC Away Wins: Washington (OK), WashingtonSt (OKST), Nevada (TT), UTEP (UT), New Mexico (TAM) -------- that's it, 5 (a combined 12-30 + not one by the B12-North)!
OOC Away Loses (I can respect a team that goes on the road): SouthFL (KU), FloridaSt (COL), Louisville (KSU), Iowa (ISU), UNLV (ISU), UCONN (BAY) ----- 6 away loses, all to teams who won't be ranked at the end of the season (maybe FSU stays in the top 25 if they don't get blow-out by UF at the end of the season)
Wins against the other 5 power conferences: Washington State (OKST away), Washington State (BAY home), Washington (OK away), Arkansas (TX home), Cincinnati (OK home), West Virginia (COL home), Illinois (MO neutral site) --------- wow, not impressive).
Best Win: West Virginia or Illinois or TCU (OK home)
That's pretty sad
