Rap Sheet: A shocking retirement

"He's amazing. I told him the other day I don't think he's human," Harvin said, according to ESPN.com. "Two weeks ago, he beat a couple guys in a race. When I got here yesterday, I told them guys they should be embarrassed."

"I got to run against Adrian and he's looking good," said wide receiver Jerome Simpson, who beat Peterson in the race. "It was neck-and-neck there. We're always talking a little trash back and forth to each other, but it was a great competition."
