Chargers still the best, but teams are closing the gap

The Chargers might have lost a little depth in the offseason, but as long as they have LT, it's hard to say there's a better rushing attack in the NFL. However, the competition is creeping up on San Diego, and the gap between the Chargers and the rest of the league is no longer as great as it once was. And it might be a little surprising to see who is closing fast in the top 10.

1. San Diego Chargers
Even though San Diego did not finish the 2007 season with the No. 1 run offense, the Chargers take the top spot in the running back rankings. They don't have the deepest running back unit, but they do have LaDainian Tomlinson, the best running back in the game. He was the 2007 MVP, has won back-to-back rushing titles and is the most feared running back in the game because of his versatility. He can align in multiple spots and create numerous mismatches for defensive coordinators as a runner and as a receiver. The overall unit took a bit of a hit with the loss of Michael Turner via free agency to Atlanta, but new backup Darren Sproles has made plays when given the opportunity.
