The last time No. 16 Oregon was 6-0 in league play the Ducks were known as the Webfoots and the league was called the Pacific Coast Conference, not the Pac-12. But Oregon (17-2, 6-0 Pac-12) reached that mark for the first time since 1925-26 on Wednesday with a 68-61 victory over Washington State, a win that required a rally from the Ducks' largest halftime deficit of the season.
