The Washington over Nebraska win was not impressive, Nebraska didn't show up and Martinez was still hurt.
Iowa beating Missouri is not that impressive, the Big 12 is not good and Iowa should have beat them anyway, they are a better team, they lost some close games they shouldn't have, but that is the way it works. Figure this out, the defense let them down in all their losses late in games, but finally made a play that they should have made, not impressive.
I would pick TCU everytime over Wisconsin. Wisconsin got forced to pass, TCU beat them up most of the 2nd half until the last drive and took Wisconsin out of their game. No other team was able to do that to the Badgers, also TCU moved up the field and if not for some poor choices on third down should have scored two more touchdowns. Nobody gave TCU a chance, it doesn't matter if they were the higher rated team, they were not supposed to win.
