Oregon coach Mark Helfrich said today that new offensive coordinator Scott Frost will call plays for the Ducks this season.

Helfrich made that disclosure while in Bristol, Conn., in one of at least 10 interviews he's doing over the course of the day as part of ESPN's "car wash" for all six Pac-12 North coaches.

"I'm still going to be involved offensively," Helfrich told ESPN's Ivan Maisel on a podcast this morning. "If I've had an area of expertise over the years, that's been it. … (Frost) is going to call plays, and we're going to be in lock-step with everything we do."

Frost, who spent the last four seasons as Oregon's receivers coach, called plays during spring practices, but Helfrich had yet to announce how things would operate in the fall. Helfrich had called plays in the spring in the past, but former head coach Chip Kelly remained the Ducks' play-caller in games.

In a chat with fans hosted by ESPN today, Helfrich said that "the aggressive nature of our program will continue. That's something that will be outwardly apparent to the onlooker." Oregon has been one of the most efficient teams in the country the last few years in areas such as fourth-down conversions and two-point tries, and apparently that will continue.

Kelly moved from the booth to the field when he became head coach in 2009. Now the Ducks' play-caller will be back upstairs, as Frost is moving from the sideline to the booth in his new role.

Presumably Oregon's backup quarterbacks will continue signaling in plays from the sideline, now getting the calls over the headset from Frost rather than from a coach standing nearby on the field.

Helfrich said offensive assistants Gary Campbell, Steve Greatwood, Tom Osborne and Matt Lubick would be heavily involved in game-planning, as the staff has been for several years.
