Adrian Peterson thinks he's the best running back in the game. Now he's getting paid like it, too. Peterson agreed Saturday to a contract extension with the Vikings that includes $36 million in guaranteed money and as much as $100 million over the next seven years if he plays that long with Minnesota. A league source told ESPN NFL Insider Adam Schefter that Peterson will receive $40 million over the first three years of the deal. Peterson also will get $1 million each time he rushes for at least 1,250 yards, a source familiar with the contract told ESPN's Schefter. Peterson has done that in each of his first four seasons, when the fewest rushing yards he had in any season was 1,298. Under the terms of his contract, Peterson can do this three times for $3 million total. He also has another $1 million in incentives based on the Vikings' regular-season and playoff results over the life of the contract.
