The biggest issue on defense for the UCLA Football team last season was stopping the run. With the Bruins losing several defenders to injuries and having issues with schemes, UCLA was not able to slow teams down. At all.
In the last three games of the season, the Bruins allowed 197 rushing yards to Utah, 235 to USC and 326 to Nebraska for an average of 252.7 yards per game. Not exactly the kind of yards you want to give up on a weekly basis.
In the off-season, Defensive Coordinator Tom Bradley looked to change things around by implementing a 4-3 formation.
