No. 4 TCU looks to keep its undefeated campaign intact and take its next step toward a berth in the College Football Playoff when it hosts struggling Iowa State on Saturday in Fort Worth, Texas.The Horned Frogs (11-0, 8-0 Big 12) have already clinched a spot in the league championship game on Dec. 3 in Arlington, Texas, where they will play either No. 12 Kansas State or No. 23 Texas.And while the Big 12 title will be up for grabs in that game, TCU has a bigger goal — beating Iowa State to remain in the top four of the CFP rankings.How TCU got to this point without a loss is a story in itself, especially in its most recent game. That’s when the Horned Frogs needed a fire-drill, last-second field goal from Griffin Kell to beat Baylor 29-28 on the road last Saturday to stay unbeaten. TCU scored the game’s final nine points over the last 2:07.Max Duggan completed 24 of 35 passes for 327 yards while leading TCU in rushing with 50 yards on eight carries, including a 7-yard touchdown. Taye Barber had a team-best five receptions for 108 yards, his second 100-yard game of the season and the fourth of his career.”The great thing about the last drive is that we were throwing all of our day-one concepts,” Duggan said. “We were throwing easy stuff that we practiced and could do with our eyes closed.”While the undefeated mark is uber-impressive, nothing has been easy for the Horned Frogs. TCU is the first team since 1975 to win seven consecutive games by 10 points or fewer.”We’ve just got a lot of fight, guys never give up,” TCU coach Sonny Dykes said. “We knew it was going to be a tough one (at Baylor). They just found a way. I think it says a lot about who they are.”The Cyclones (4-7, 1-7 Big 12) head to the Dallas-Fort Worth Metroplex to finish their season. A 14-10 loss to Texas Tech last Saturday assured that Iowa State would not play in a bowl game for the first time since 2016.
