Wisconsin has put up a lot of points recently and at times during the season -- against the Little Sisters of the Poor. The Cheese Heads only played 3 times with half a defense --- Ohio State, Arizona State, and Iowa --- and scored 31, 31, and 19. The Badgers lost to a very weak Michigan State team.
Wisconsin also is pretty weak away from home --- struggled with UNLV, lost to Michigan State, won by a point at Iowa, only scored 34 vs. Purdue, and only won by 20 over Michigan.
Wisconsin just knows that it needed to RUTS to get ahead of Ohio State and Michigan State to get the Rose Bowl. And there will be 60k Cheese Heads at the Rose Bowl....
TCU has nothing to fear from Wisconsin.
Stanford is a nice team, but ..... has put up its points vs. a weak OOC schedule and a weak Pac-10 (which is on track to have 3 to 4 bowl eligible teams). Luck is a decent QB, but AD is just as good.
While both teams are dangerous (as are Oregon and Auburn), I just don't see TCU having problems with any of them.
