Andy Dalton threw a touchdown pass and ran for a score, linebacker Tank Carder swatted down a 2-point conversion pass attempt with 2 minutes to play, and No. 3 TCU completed a perfect season with its first Rose Bowl victory, 21-19 over fourth-ranked Wisconsin on Saturday.

Bart Johnson, of Brownwood, caught an early TD pass and recovered a late onside kick for the Mountain West champion Horned Frogs (13-0), who followed up their second straight unbeaten regular season by busting the BCS in dramatic fashion.

Dalton passed for 219 yards for TCU, which won’t win the national title after Auburn and Oregon meet in the BCS championship game in nine days.

These ferocious Frogs still proved they can play with anybody on college football’s biggest stages.

Montee Ball rushed for 132 yards and a late score for the Big Ten co-champion Badgers (11-2), whose loss capped a nightmare New Year’s Day for their conference.
