After Ron Rivera stole away the San Diego Chargers Secondary Coach and Assistant Head Coach Steve Wilks, Ron Meeks (who had been coaching the Carolina Panthers Secondary under Ron Rivera) found himself without a job. What better place to interview for a new job than where his replacement came from.
Meeks was a Defensive Coordinator in the NFL for close to 10 years, but when Rivera signed on to be the Head Coach of the Panthers he demoted Meeks to Secondary Coach. Ron could've possibly found a Defensive Coordinator position somewhere, but his long-time ties to Norv Turner seem to be a driving force behind why he's decided to sign on to coach the Secondary for the Chargers in 2012.
Meeks started his NFL career as a defensive assistant with the Dallas Cowboys in 1991, with Norv Turner on the staff as well. Before eventually becoming the Defensive Coordinator for the Indianapolis Colts, where he won a Super Bowl with Tony Dungy, Meeks also coached the Secondary for Norv Turner's Washington Redskins teams.
As long as nobody else on the defensive staff runs to the Carolina Panthers (looking at you, Don Johnson), all that should be left for John Pagano is to find a replacement Linebackers Coach.
