CARSON, Calif. (AP) For Alvin Kamara to see meaningful playing time this season for the New Orleans Saints, the rookie running back is going to have to offer something different than Adrian Peterson and Mark Ingram.

That's exactly what Kamara showed by running for a 50-yard touchdown on New Orleans' first offensive play and leading the Saints to a 13-7 win over the Los Angeles Chargers on Sunday night.

Kamara burst off the left side, stepped over a diving defender that grabbed at his ankles and maintained his balance to score the game's only offensive touchdown 1:13 into the first quarter.
