"Laughter may be the best medicine, the best vitamin supplement, the best energy drink. Laughter may be the reason Willis McGahee, the Broncos' soon-to-be-30 running back, believes he has plenty of carries left in the football tank.

"I was out there just laughing," McGahee said about playing against Cincinnati on Sunday. "I felt good. I felt happy. The game was still so fun to me. This is what I want to do, where I want to be. If it still feels like that, you know you should still be doing it.

"My body feels great, my mind is right, it was good to come through, get to work and get the job done when they needed the job done."

McGahee, 29, pounded away for 101 yards on 28 carries, helping Denver overcome a slew of injuries, including one to running back Knowshon Moreno.

It was McGahee's first 100-yard rushing game since the 2009 season finale, when he was with Baltimore, and the most carries he's had in a game since the 14th game of the 2007 season. It also was a chance for the 235-pounder to show he could run hard in the middle of the field, take care of the ball and push the pile."
