The Arizona Cardinals and Tyrann Mathieu could agree upon an extension that makes him the richest safety in the NFL.

"They view him as one of the faces of the franchise and their community efforts," Ian Rapoport said. "... From what I am told a new payday is expected to make him among the highest paid, if not the highest-paid safety in the NFL and don't be surprised, if all goes well, if this is done before everyone breaks for the summer."

Seattle's Earl Thomas earns $10 million per season, New England's Devin McCourty has the highest guarantee at $22 million and Eric Berry is under the franchise tag at $10.8 million in Kansas City.
