Spotlight on special teams alterations

In recapping the Patriots' 22-21 loss to the Dolphins, a few special teams changes were notable because of the ever-evolving makeup of the team's roster:

1. Starting inside linebacker Jerod Mayo, who was part of every defensive package and thus played every snap, was taken off the punt coverage team. Rob Ninkovich took his spot.

2. The alignment of the kickoff return unit was tweaked by adding running back Sammy Morris to the front line and leaving two players in the wedge (Chris Baker, Dan Connolly) instead of three. The changes once again didn't produce the desired result, as the unit averaged only 19.8 yards per return.

3. With core special-teamer Bret Lockett inactive with a groin injury, first-year cornerback Kyle Arrington filled his role as gunner on the punt coverage team.

4. Rich Ohrnberger stepped in for the injured Stephen Neal (ankle) on the field-goal protection unit.
