In losing Myles Jack, the UCLA defense lost more than just a hard-hitting linebacker.
Jack's skill set allowed him to be a force against the run and also to blanket receivers and backs in pass coverage.
With him on patrol, the Bruins did not have to worry about changing personnel based on whether they faced a run or pass situation.
"We've been able to play one personnel group against any offensive group, whether it has been two backs, a tight end, two wide receivers or one back and four wide outs," UCLA Coach Jim Mora said.
