The Chargers have a one-two punch for at least another season (and probably longer) that could rival any in the league if both Ryan Mathews and Mike Tolbert stay healthy.
The pair averaged a combined 4.2 yards per carry in 2010. The plan going forward would be to rotate them based on who’s hot and which defense the Chargers are facing.
Considering that and the money he can make elsewhere, it seems unlikely that Darren Sproles will continue as the third-down back. That leaves Curtis Brinkley, who will certainly be given a chance. But the Chargers could also keep him on the practice squad and bring in a veteran.
