UCLA quarterback Josh Rosen was named the Pac-12’s Freshman Offensive Player of the Year, an unsurprising development given his stellar first season behind center for the Bruins.

On the way to completing 59.5 percent of his passes for 3,350 yards, 20 touchdowns and nine interceptions, Rosen also set a school record by throwing 245 consecutive pass attempts without a pick. He also set a new UCLA single-game mark with 34 completions against Cal on Oct. 22.

USC linebacker Cameron Smith was the conference’s top defensive freshman, while Stanford running back Christian McCaffrey and Oregon defensive lineman DeForest Buckner were named Offensive and Defensive Players of the Year, respectively.

Stanford’s David Shaw and Washington State’s Mike Leach shared the league’s top coaching honor.

Earlier on Tuesday, UCLA placed nose tackle Kenny Clark on the All-Pac-12 first team, as well as seven other players on the second team.
