"I'd say 2,200 yards (this season),'' wife Ashley Peterson said of her husband's potential in 2015. "I think he can definitely do it. His mind-set is totally different than anybody I've ever met. He's very determined; he's very strong-minded; he's very strong-willed. I think he has a goal in mind and he's not going to stop until he reaches that goal. ... I think he's going to go out there and surprise a lot of doubters and the naysayers.''
