Saturday’s Rose Bowl game, the 97th in its long history, boasts the only undefeated team, Texas Christian, that didn’t make it into this year’s Bowl Championship Series title game (Auburn versus Oregon on Jan. 10 in Glendale, Ariz.). Third-ranked, 12-0 TCU, the Mountain West Conference champ, will make its first-ever appearance in Pasadena against 11-1 Wisconsin of the Big Ten. The Badgers are fourth-ranked in most polls. TCU's Horned Frogs haven’t played a more important game since 1939, when as the nation’s No. 1 team they defeated Carnegie Tech, 15-7, in the Sugar Bowl. This marks Wisconsin’s seventh trip to the Rose Bowl, but its first since 2000. In a statistical oddity, TCU and Wisconsin have both averaged 43.3 points per game, fourth best in the country. Coverage begins at 5:00 p.m. ET on ESPN. To prep for the game, try your hand at this 20-question Rose Bowl quiz.
