Josh Rosen’s historic debut season added another accolade Tuesday as he was named the Pac-12’s offensive freshman of the year.

Rosen became the first UCLA true freshman to start a season opener at quarterback in September against Virginia and broke nearly every school single-season true freshman passing record.

The 6-foot-4, 210-pound signal caller also set a school mark earlier this month for consecutive passes without an interception, a streak of 245 pass attempts. Spanning more than a month, it was snapped last Saturday in a loss at USC. Drew Olson held the previous record of 199 passes without an interception in 2005.

He is the first UCLA player to receive the conference’s freshman of the year honors since Myles Jack was named the freshman offensive and defensive player of the year in 2013.

Rosen finished the regular season by throwing for 3,350 yards, 20 touchdowns and seven interceptions, completing 53 percent of his passes. He also rushed for two touchdowns.

Following training camp in August, Rosen, a former five-star recruit from St. John Bosco High, was named the Bruins’ starter over Jerry Neuheisel, ending what was once a four-man competition that began in spring practice to replace Brett Hundley.
