What we learned: Week 13

What did we learn from Oregon's 42-16 loss at Arizona? Not much good.

No BCS bowl for Oregon: The story might have been overblown, but WR Josh Huff and RB De’Anthony Thomas said this past week that they weren't excited by the possibility of playing in the Rose Bowl. Well, the Ducks won't be playing in the Rose Bowl after losing to the Wildcats, which made Stanford the North Division champion. In fact, their streak of four consecutive BCS bowls is almost certain to end.

No Heisman for QB Marcus Mariota: Mariota played pretty well against Arizona, but he threw his first two interceptions of the season -- the first not being his fault in the least -- and the dispiriting loss will end his Heisman Trophy candidacy. Maybe going down like this will inspire to return for his junior season instead of entering the NFL draft?

Some questioning of coach Mark Helfrich: While it might not be completely fair to question the program under a first-year head coach so quickly, Oregon suffering its first defeat to an unranked team since 2009 and its worst defeat since 2008 will cause some to wonder if the Ducks would have played so poorly under Chip Kelly. That's Helfrich’s burden, and he knows it: Kelly left behind a team that was expected to contend for the Pac-12 and national titles, so he had little margin for error when it came to defining this season as a success.
