Adrian Peterson has done plenty over the years for the Minnesota Vikings and he has never publicly balked at taking on even more responsibility.
How about special teams? Of course, he'd love to do that, too.
Peterson said Wednesday he has been lobbying to be on the field-goal block team. He also said he ''wouldn't mind getting back there'' as a kickoff returner, a role he held occasionally as a rookie but not since 2008.
Approval from coach Leslie Frazier is unlikely. But special teams coordinator Mike Priefer says there is ''absolutely an opportunity'' for Peterson to return a kickoff if the Vikings are searching for a spark in a desperation situation at the end of a game.
