The Miami Dolphins have locked in one of their most dynamic offensive weapons, signing running back De'Von Achane to a four-year contract extension. With this deal, Achane—who had one year remaining on his rookie contract—is now under team control for the next five seasons.

Reports vary slightly on the financial details. According to NFL Network's Ian Rapoport, the extension is worth $64 million, with a potential max value of $68 million. Meanwhile, Jordan Schultz reports the base deal at $68 million. That difference translates to a new-money average of either $16 million or $17 million per year—but either way, it places Achane at No. 3 among all NFL running backs in average annual value.

Only two backs currently top him: Philadelphia's Saquon Barkley ($20.6 million per year) and San Francisco's Christian McCaffrey ($19 million per year). That's elite company for a player who has quickly established himself as a game-changing force in Miami's high-powered offense.

The fine print of the contract will ultimately determine its true value, but the big picture is clear: Achane has earned the second contract he deserves. For running backs, especially those coming off their third NFL season, securing that second deal early is critical. The Dolphins recognized that urgency and acted accordingly, ensuring one of their brightest young stars stays in aqua and orange for years to come.
