According to the Chargers, Jackie Battle vaulted Ryan Mathews on the team's official depth chart because "he just started last week, so that's why he's there."In other words, it's semantics. Although the Chargers' actions have officially gone beyond simple message sending, it's clear they're not on the verge of a sea change in the backfield. Battle's big week came against a non-competitive Chiefs team, and the 29-year-old spare part simply isn't talented enough to out-carry Mathews when games are on the line. Beat writer Michael Gehlken "wouldn't read into" the depth chart shenanigans, and believes it's "likely only a matter of time" before Mathews moves back ahead of Battle. However, Gehlken does expect Battle to remain involved, perhaps as the goal-line back. That would be unideal for Mathews' fantasy value, but he's simply too talented not to re-emerge as a RB1, and soon. Mathews remains the top buy-low candidate in all of fantasy football.
