10/13/2011 - SCOUTING THE DEFENSE: The Bears' defense had been awfully good against the run until Oregon's LaMichael James sliced through it for 239 rushing yards on Oct. 6. The Ducks rushed for 365 yards, more than three times the previous season high against Cal. The Bears' run defense was particularly vulnerable on the perimeter, as Cal simply could not handle the Ducks' speed, although USC may not be able to exploit the flanks as effectively as Oregon did. The Bears' pass defense has been its biggest weakness, getting carved up by every good quarterback it has faced Colorado's Tyler Hansen, Washington's Keith Price and Oregon's Darron Thomas. But all three were on the road, and Cal's pass defense has been much better at home since Clancy Pendergast became defensive coordinator prior to last season. Offensively, when Cal must convert its red-zone opportunities into touchdowns, something it has been unable to do in conference play. PLAYERS TO WATCH: DE Ernest Owusu made a number of big plays against Oregon, including a sack and a batted-down fourth-down pass that helped Cal stay in the game for a half. He needs to apply pressure to Barkley.
