There's a serious leadership void on the Raiders' defense now
The Oakland Raiders defense just lost two men who know what it takes to win a title.
Safety Charles Woodson and Justin Tuck were invaluable pieces in the team's turnaround. They retired over the span of two days earlier this week.
It left former Super Bowl MVP Malcolm Smith as the only Raider on-roster with a Super Bowl ring. And only two other starting Raiders -- nose tackle Dan Williams and safety Nate Allen -- have more than four years experience and are under contract for 2016.
New defenses voices must fill a sizable leadership void now. It falls on soft-spoken star Khalil Mack or ex-rookie Mario Edwards Jr. or Smith or Allen.
None should be expected to carry the same weight as Woodson or Tuck. So it might be helpful for the team to import defenders who've climbed the proverbial mountain before.
