Greg Williams is as known for his participation for "Bountygate" as his defensive expertise.

The coach who was once suspended for allegedly paying New Orleans players for dirty hits is now the new defensive coordinator for the St. Louis Rams.

Williams spent last season with the Tennessee Titans, revamping their defense to a league-topping force and has a rep for turning defenses around.

Jeff Fisher has been looking for the right time to bring Williams in to coach a young defense already on the rise.
