The Miami Dolphins have officially declared that star running back De'Von Achane is not available for trade, according to General Manager Jon-Eric Sullivan. The team considers Achane a foundational pillar of their roster and is actively prioritizing a long-term contract extension for him. Negotiations are reportedly trending in a positive direction, and the athlete recently arrived at the team facility as a gesture of good faith during the ongoing talks. Miami is eager to finalize a deal soon to get ahead of the market before other top running backs from the same draft class sign their own expensive contracts. These efforts follow an impressive Pro Bowl season where Achane established himself as one of the most efficient and productive offensive players in the league.
