The fourth of 10 quick updates on offseason Pac-10 goings on.
Oregon in a sentence
The return of quarterback Jeremiah Masoli and running back LeGarrette Blount after a dominant Holiday Bowl performance against Oklahoma State have the Ducks in the top half of most preseason rankings, overshadowing questions on both lines as well as receiver.
The big issue
The Ducks rolled up 42 points and 485 yards per game in 2008 in large part because of an outstanding offensive line. Three starters are gone -- two whom were drafted -- so rebuilding this unit will be the critical concern in preseason camp.
Quick hit news
Four potential starters/key contributors transferred in offseason: defensive tackle Tonio Celotto (Nevada), receiver Aaron Pflugrad (Arizona State), quarterback Justin Roper (Montana) and receiver Chris Harper (Kansas State).
New head coach Chip Kelly hired Mark Helfrich, a Medford, Ore., native, away from Colorado to coordinate the offense. Kelly, the offensive coordinator under former coach Mike Bellotti, will still call plays.
Oregon signee Cliff Harris, an ESPNU 150 cornerback out of Fresno, pleaded no contest last week to obstructing a police officer in the line of duty -- a misdemeanor -- and was sentenced to one year of probation and fined $300, according to the Fresno Bee, which won't prevent him from playing for the Ducks this season.
