Byron Marshall is playing like a starter while De'Anthony Thomas is sidelined.

The running back for No. 2 Oregon ran for 192 yards and three touchdowns against Washington State on Saturday night.

Marshall has four straight games with more than 100 yards rushing, bringing his average to 106.57 yards, good for 21st in the nation.

He credits a simple philosophy for his success. He says "If you're not getting better, you're getting worse."

Marshall, a 5-foot-10 sophomore, has rushed for 759 yards and nine touchdowns on 111 carries. He called his performance against Washington State the best game he's ever had.

Thomas hurt his right ankle on the opening kickoff in Oregon's 55-16 victory over California back on Sept. 28, slipping on slick turf from a driving rain.
