Pac-12 Conference play tips off on Wednesday in Berkeley, Calif., when Cal hosts Southern California in a matchup of teams seeking to end losing skids.For USC (4-3), the early-season swoon is less pronounced than its conference counterpart’s slide. The Trojans opened last week’s Battle 4 Atlantis tournament in the Bahamas with an 82-76 win over BYU for their fourth straight victory after dropping a surprising season-opening decision to Florida Gulf Coast.USC lost its next two to close out the Battle 4 Atlantis, however, falling to Tennessee 73-66 in overtime on Nov. 24 and 64-59 to Wisconsin in the third-place game the next day.Cal (0-7) opens conference competition looking for a reboot of sorts. The Golden Bears went winless through the season’s opening stretch, which included losses to Southern University and Division I newcomer UC San Diego.A pair of losses to TCU and Clemson at last week’s Emerald Coast Showcase in Florida have sent Cal into the league opener on a seven-game skid.”We’re a wounded team right now,” Bears coach Mark Fox said in his postgame press conference following Cal’s 59-55 loss to Texas State on Nov. 21. “We’ve had a miserable start to the season.”Offensive woes are hindering the Golden Bears, starting with turnovers. Cal is averaging a turnover on more than a quarter of its possessions, per KenPom.com metrics.
