Ohio St dominated a team everyone thought would win going away. Wisconsin beat Miami more soundly than the score indicated. Northwestern should have won their game. Minnesota lost by 1 point. Penn State won.
Iowa either wins or covers the 4. Book it!
Although what you stated does favor Iowa, I think it is only in a very slight way.
The reason I say this is because I have tremendous, tremendous respect for the quality of this GT team........more so then any team the Big Ten has faced this year in a bowl game(yes, I think GT is a better team then LSU and OREGON).
Although the GT defense may only be average, their offense can be as potent as ANY team in the nation.
As I stated once or twice earlier, watching the GT offense do battle against the outstanding IOWA defense should be something every true college football in America should be looking forward to.
