Lambert’s second-half collapse last Friday at Centennial prevented an undefeated start to region play for the Longhorns, and it came in devastating fashion. Centennial scored 14 points in the final eight minutes, including a game-winning 5-yard touchdown run by Casen Conway with 1:31 remaining. Trevor O’Brien’s effort was an encouraging sign for a Lambert offense that had yet to run the ball with any success.
