ESPN reports reports that new Titans running back coach Sylvester Croom said he wants to bring in another running back to take the load off Chris Johnson in 2013. “I truly believe if you’re serious about running the football, you’ve got to have two guys actually both able to carry the load during the season,” Croom said. “... If you’re going to really run, I’m talking 30-plus times a game, there aren’t many that can do that for 16 games anymore, their bodies can’t take it.” Croom said he doesn't want to take Johnson off the field. The report says "they still want to feature the explosive guy who can score any time he touches the ball from a handoff or a catch." But the Titans do want to have a second guy who can do other things in a different kind of role with a different style that can help the team in certain situations.
