If anything is true about Oregon basketball, it is that the Ducks are difficult to figure out.They stunned then-No. 9 Arizona in blowout fashion on Jan. 14. They handed Utah a loss in Salt Lake City earlier this month. But on the flip side, the Ducks have suffered through poor shooting games in losses to lower-echelon conference teams, including Stanford last Saturday.Host Oregon (11-9, 5-4 Pac-12) gets a shot to atone for a 41-point effort at Colorado earlier this month with a rematch against the Buffaloes in Eugene, Ore., on Thursday.The Buffaloes (12-9, 4-6) blasted Oregon 68-41 at home on Jan. 5, with the Ducks shooting 26.9 percent and making just 1 of 14 3-pointers. This time, a Ducks’ win would keep Oregon in the top half of the Pac-12 standings.Oregon is coming off a split in the Bay Area, with a blowout win at Cal and a loss at Stanford, where Jermaine Couisnard’s 18 points led the way in defeat.”I complimented the guys on how hard they played the last two games (before Stanford) and we just didn’t have that same kind of effort, that same kind of focus,” Oregon head coach Dana Altman said.
