Last week UCLA and Arizona were ranked ahead of OR, even though the Ducks have beaten Arizona and tied the season series with the UCLA Bruins. Jason Gardner had 22 points in that game, while Loren Woods had 16 points, 12 rebounds and four blocks. Jordan Bell tops in rebounds with 7.9 while Dylan Ennis leads in assists with 3.2 per game.
