Stanford switches QBs, will start Keller Chryst at Arizona

After three losses in the past four games, Stanford head coach David Shaw decided it was time for a change.

Shaw said Burns has played well at times, particularly against USC and during the game-winning drive against UCLA.

Stanford (4-3, 2-3 Pac-12) has just four touchdowns from its offense in the past five games and ranks last in the conference in scoring offense and total offense.

Burns has thrown for five touchdowns and seven interceptions in his seven starts.

Burns’ inconsistency is but one of a number of problems that have beset the offense, including a line that hasn’t pass-blocked very well and hasn’t consistently opened holes for tailbacks Christian McCaffrey and Bryce Love.

Holder missed three games with a shoulder injury he suffered against UCLA.

Chryst completed 5 of 9 passes with one touchdown in four games.

Playing mainly one or two series in his appearances, he has completed 7 of 18 passes with no TDs and one interception.

Chryst, who was not made available to discuss his first collegiate start, is the son of former 49ers offensive coordinator Geep Chryst and the nephew of Wisconsin head coach Paul Chryst.

Trent Irwin, the team’s leading receiver, agreed with Shaw that the whole offense should share the blame for the lack of production, but he said, Sometimes you need to change a little bit up.
