Titans' second-year running back Bishop Sankey is reportedly "the odds-on favorite" to begin the season as the starting back. If for nothing else, just the fact that he has a full year under his belt makes him the top candidate. The Titans also added rookie RB David Cobb this offseason. He is a popular pick to take over the lead-back job at some point this season. Antonio Andrews is also in the mix for backup duties. Dexter McCluster is expected to have a role but he's little more than a specialist.
