Adrian Peterson aims to be ready for the start of the 2012 regular season. His top backup, Toby Gerhart, has no reason to doubt that will be the case. "I think he will be," Gerhart said. "You can never be surprised with Adrian. The way he comes to work every day, the way he pushes himself. I mean, he was flying around, straight-line speed, moving out there. Racing Percy (Harvin) up the hill, doing conditioning stuff. I haven't seen him in a couple of weeks now, but I'm sure he's continued to make leaps and bounds in progress. "I wouldn't be surprised if he's ready. You can never count Adrian out." Peterson will be nine months out from major knee surgery at the start of the season and likely will be limited.
