I imagine it has at some point, but I'm not going to go through the process of finding outThe game was as good as it could be last year and both Iowa and Iowa State beat the team that eventually won their conference in OSU and OU, has that ever happen in the same season?
The thing I found impressive was that when TCU and OU played for the Big XII championship, both had only one loss on their record....and in both cases, it was ISU.
THAT hasn't happened a lot in the past.
