The San Diego Chargers are 3-1 for the first time in five seasons under Norv Turner, and they've done it with workmanlike performances rather than a lot of flash and dash. Philip Rivers was 21 of 31 for 307 yards and one touchdown, Mike Tolbert ran for another score and the Chargers knocked out Miami quarterback Chad Henne on the way to beating the winless Dolphins 26-16 on Sunday.
