CLEMSON, S.C. (AP) — Coach Gary Patterson wants to bust up talk about No. 15 TCU’s BCS potential.

“I’m not drinking that Kool-Aid,” Patterson pledged.

The Horned Frogs showed off their stellar defense and bolstered their Bowl Championship Series credentials with a 14-10 victory at Clemson on Saturday.

Andy Dalton threw two TD passes in keep the Frogs (3-0) perfect. It was only a week ago that Mountain West Conference heavyweights — Utah and BYU — stumbled to BCS-bid conference opponents.

That left TCU carrying the banner for the MWC heading into Death Valley to play Clemson for first time since 1965.

The Horned Frogs lived up to their reputation as rock-solid defenders. They held Clemson to 117 yards in the second half and stopped the Tigers twice on fourthquarter drives inside the TCU 20.

“Our defense has played great. It’s nice to have them on our team,” Dalton said. “On offense, you don’t want to have games 14-10. But it’s nice to come out with wins like that.”

TCU trailed 10-7 entering the fourth quarter as it had its own problems against a Tigers defense that held Boston College to 54 yards a week earlier.

That’s when Dalton ended a 56-yard drive with a 25-yard TD pass to Antoine Hicks to move in front with 12:46 left.

TCU kept the Tigers (2-2) off the scoreboard on their two best secondhalf chances as a steady rain soaked Death Valley. The initial drive ended with Richard Jackson’s first field goal miss — he had made his last nine — in three games.
