The Oregon Ducks continue to be heavy favorites to win in Autzen despite the injury suffered to start tailback LaMichael James. The Arizona St. Sun Devils might be their competition in the Pac-12 Championship game, but Vegas doesn't think quite highly of them yet compared to the defending conference champions.
Oregon is currently positioned as two touchdown-plus favorites, favored by 14.5 points against ASU. You figure the line would've been a bit higher if LaMichael was in action. This might not be a terrible time to place bet on the Sun Devils if you believe ASU has the horses on defense to hold their offense down and you're truly a believer that James is the engine that makes the Ducks go.
Otherwise, this line seems about right. Just remember that you should be very, very wary of Oregon not covering a line at home, something that they've done a really good job of doing as of late, regardless of quality of opponent.
