EUGENE, Ore. (AP) -- Kenjon Barner rushed for 104 yards and two touchdowns, and No. 2 Oregon easily took care of Colorado 70-14 on Saturday in advance of next weekend's Pac-12 showdown with 10th-ranked USC.
De'Anthony Thomas rushed for another score and added a 73-yard punt return for a touchdown before most of the Ducks' offensive starters were pulled midway through the second quarter. Redshirt freshman quarterback Marcus Mariota passed for 136 yards and two TDs.
The Ducks (8-0, 5-0 Pac-12) built a 56-0 lead by halftime and their 70 points were the most they'd ever scored against a conference opponent. It was Oregon's 11th straight overall victory dating to a 38-35 loss at home to USC last season.
Christian Powell rushed for 127 yards and two touchdowns for the Buffaloes (1-7, 1-4), who lost their fourth straight.
