Of the areas of concern entering 2014, the general manager focused on defensive improvement.
"We had a lot of tough days defensively -- a tough season," Emery said. "There are no excuses for it.
"All aspects are on the table to be evaluated. We want a physical, fast, playmaking defense. A defense that causes disruption. I saw that in the first three games."
Trestman said "everything is on the table three days into a through process" regarding defensive coordinator Mel Tucker.
Emery said the defense will be younger in 2014, and a focus of the team's draft plans.
