The Chargers will turn Ryan Mathews into their workhorse running back in 2012.
However, they will need a few solid backup running backs to help spell Mathews whenever he's tired.
The Chargers signed Ronnie Brown, Jackie Battle and undrafted free agent Michael Hayes.
Additionally, the Chargers drafted Edwin Baker out of Michigan State in the seventh round.
The Chargers also have Curtis Brinkley returning.
Chargers fans expressed excitement when Brown was signed. Unfortunately, it looks like Brown is now an over-the-hill running back.
The Eagles were similarly excited when they brought in Brown last year. Their excitement was quelled when Brown committed what might be the worst mistake of the season when he attempted pitching the ball to a teammate while being tackled.
Battle might be a more interesting addition to the roster than Brown.
Last season, Battle showed a bit of power running the ball for the Kansas City Chiefs. That is what the Chargers need in a backup for Mathews.
Although he doesn't receive much attention, Brinkley also showed the ability to produce in spot duty last season.
It will be interesting to see how Baker performs during training camp. He left Michigan State early after a disappointing junior season, but he has a lot of talent.
Hayes is a wild card in the equation. No one knows too much about him, but he showed the ability to score touchdowns in college, as he reached pay dirt 15 times in just 182 touches.
The Chargers have a big decision to make when they decide which running backs to keep on the roster.
