Ryan Mathews waits for his turn

The Raiders took all their frustration about their stagnant running game out on the Chargers Sunday.

By the time the carnage was done, the Raiders out-gained San Diego 251-22.  If that wasn’t embarrassing enough for the Chargers, their first-round pick Ryan Mathews didn’t play a snap in the game despite being healthy.

“I’m good,” Mathews said via the San Diego Union-Tribune.  “I was ready to go in. I’ll just wait my turn. I’m a young running back. I know what they’re doing. It’s all a learning process.”

Chargers coach Norv Turner says Mathews just doesn’t know the team’s protections as well as starter Mike Tolbert.  Still, it has to be a disappointment they can’t get the kid on the field in a game where Darren Sproles left in the second quarter.

The Chargers gave up a huge bounty to move up for Mathews and draft him No. 12.  They haven’t got a lot in return for the investment this year, and they are running out of time to do so.
