Costello to start against Washington State November 3, 2017 0 Comments Share tweet Samuel Curry Desk Editor By: Samuel Curry | Desk Editor Head coach David Shaw announced Thursday that he will start sophomore quarterback K.J. Costello over senior Keller Chryst in Saturday’s matchup with no. 25 Washington State. The decision comes a week after a near upset at Oregon State in which Chryst threw 33 passes for 16 completions, 141 yards, an interception and the game-winning touchdown. This is the third time Shaw has changed quarterbacks midseason in six years. Chryst has had a disappointing year, throwing for a 54.2 completion percentage, eight touchdowns and four interceptions in six full games on the season. He threw 10 touchdowns and two interceptions last season with a similar amount of playing time. Costello has thrown 67 passes for 43 completions and 492 yards this season, he has a quarterback rating of 145.6 to Chryst’s 123.1 and has yet to throw an interception in his career. In his lone start this season against Arizona State, he completed 15 of 24 passes for 173 yards and a touchdown in a 34-24 win. Costello’s second start of his career kicks off in Pullman at 12:30 p.m. and will be broadcasted on Fox.
