Chargers head coach McCoy adds 2 assistants

New Chargers head coach Mike McCoy added two more assistants to his staff Wednesday, bringing Ron Milus in from Denver to coach the San Diego secondary and tapping Cleveland's Kent Johnston to serve as strength and conditioning coach.

Milus spent the last two seasons coaching the Broncos' secondary. The Broncos had one of the NFL's best defenses last season and they led the NFL in fewest yards allowed per pass play (6.4).

Johnston was the strength and conditioning coach for the Browns for the past three seasons.
