Halliday, a redshirt freshman from Spokane, Wash., came off the bench to throw for 494 yards and four touchdowns in the Cougars’ 37-27 win over Arizona State. Halliday entered the game on WSU’s third possession and finished the night 27-of-36 with no interceptions. His passing total was the second-highest in school history and shattered the previous freshman mark of 385 yards, held by Drew Bledsoe. Halliday’s 494 yards also marked the highest total by a Pac-12 quarterback this season, the 10th-best passing total in conference history and the most yards ever thrown by a freshman in the conference.
