'Credibility' push among TCU challenges en route to CFP

TCU reached the College Football Playoff for the first time. The Horned Frogs went undefeated until the Big 12 championship game. They will play No. 2 Michigan on Saturday. Michigan is favored by more than a touchdown. TCU coach Sonny Dykes says his team has always been in a "fight for credibility"  in the past. The team played 11 weeks in row and had to play nine conference opponents.
