After all the drama, Chip Kelly is leaving Oregon

Oregon responded by assuming the "Next Man In" philosophy that Kelly had always preached at Oregon for replacing key players.

Kelly had barely boarded a flight for Philadelphia when the Ducks swung the search for his replacement into gear. A job posting for "Head Football Coach" appeared within hours on the university's website.

"We're here moving forward. We're not going to worry about what happened. He made a decision that was best for him and we wish him well," athletic director Rob Mullens said. "He's been great for Oregon football and we're moving on."

Mullens said Wednesday that he had already been contacted by search firms, although he had not heard from any individual candidates outside the program.

He set no timeline for replacing Kelly, except to say the Ducks will "move as fast as we can" — much like the team's warp-speed offense under Kelly.

"We had already done a lot of groundwork, we had already started the process, knowing that Chip was going to be talking to the Eagles, Bills and Browns. We had geared up our process. We had obviously shut it down, but it's easy to click right back on."

A person close to the team who spoke on the condition of anonymity because the coaching search is ongoing told The Associated Press early Wednesday that offensive coordinator Mark Helfrich was still considered the "frontrunner." Under Oregon state law, the school must also interview at least one qualified minority candidate for the job.

Mullens acknowledged there were internal candidates, but there was no "leader in the clubhouse."

"The expectation for this program has shifted," Mullens said. "We want to win Pac-12 championships. We want to win BCS bowls."

Kelly set the bar high.

Kelly was 46-7 in four years as head coach at Oregon. The Ducks have been to four straight BCS bowl games — including a bid for the national championship against Auburn in 2011 — and have won three Pac-12 championships.

He originally came to the Ducks in 2007 as offensive coordinator under head coach Mike Bellotti. Kelly was selected to be Bellotti's successor before Bellotti left the job.

Oregon finished last season 12-1. The team was ranked No. 1 and appeared headed for another shot at the national championship until a 17-14 overtime loss to Stanford on Nov. 17. The Ducks wound up No. 2 in the final AP poll after beating Kansas State in the Fiesta Bowl early this month.
