Harvey, a former college quarterback before he became a high-volume running back at UCF, showed the versatility Payton coveted in him before the draft. The rookie scored on a run off a direct snap, an explosive rush when he showed his top-end speed and then on a reception.

Dobbins, who signed a one-year deal in June to join the Broncos, said he hopes to continue to show the lead-back capabilities he has at times this season.

"I'm proving myself right that I made the right decision coming [here]," Dobbins said. "To everybody here ... offensive line is amazing, the defense is amazing, ownership is amazing, maybe I was born to be a Bronco, it just took a little time.

"I want to be a great team. I want to be like the Chiefs or like Detroit - we're proving ourselves to be one of those teams."
