I went back as far as 2011 when they Yewts joined the PAC12. The only OOC loss to a non P5 was to Utah State. They had wins against all OOC P5 teams (Georgia Tech, Michigan 2x, Indiana, West Virginia) and losses to Texas and NW in bowl games. Bottom line, we haven't beaten them since 2009 nor since they've joined the "weakest P5" conference.
