It is well-known that Adrian Peterson is entering the final year of his contract. What kind of money might he get once he finally signs an extension? Well, you -- and Adrian -- might be interested in the terms of the deal Chris Johnson of the Titans reportedly just inked. Per ESPN:

Holdout running back Chris Johnson and the Tennessee Titans agreed to a four-year extension on Thursday, the team confirmed.

A league source told ESPN NFL Insider Adam Schefter that the extension is worth $53 million with $30 million guaranteed. The extension will be tacked on to the two years he had remaining on his previous contract, putting him under the Titans' control through the 2016 season.

Johnson will receive $31 million over the first three years of the extension. Carolina Panthers running back DeAngelo Williams, who signed a five-year, $43 million contract earlier this offseason, will get $30 million over the first three seasons of his deal.

So if he earns every penny of the extension, that's about $13 million per year. Regardless, he is guaranteed $30 million. Will Peterson be worth more or less? Since he's in the last year of his deal, we have to imagine the overall length will be longer and the amount will be more. Stay tuned.
