A recent practice revealed that Da'Rel Scott had run more than any Giants running back. Barnes filed this report to coach Tom Coughlin (who we're not certain even uses e-mail), and he pondered it.

About 35 players wore the devices this offseason. No, they aren't being followed around town. It's simply a way to help the world champions maintain their edge.
