The Los Angeles Chargers still have an obvious hole to sort out along the offensive line, and training camp hasn't done much to settle it yet. The starting left guard job remains up for grabs, with five players rotating through the competition and no clear frontrunner emerging. Still, getting the right five players working together up front will make a difference, particularly for an offense that's trying to find its rhythm. Mike McDaniel, the Chargers' new offensive coordinator, has been particularly high on the second-year running back. Hampton already showed promise during his rookie season, but the Chargers seem to think there's another level available.
