The Detroit Lions have signed wide receiver Amon-Ra St. Brown to a landmark four-year contract extension worth $120 million, which includes $77 million guaranteed, making it the highest guarantee for a wide receiver in NFL history. This deal, negotiated by St. Brown's agent Joby Branion of Vanguard Sports Group, positions St. Brown among the top earners in the league, equating to $30 million per year, matching Tyreek Hill and surpassing other notable receivers like Davante Adams and Cooper Kupp. The extension not only reflects St. Brown's significant impact on the team but also sets a new benchmark for future negotiations for receivers like Justin Jefferson, CeeDee Lamb, and Ja'Marr Chase. The announcement coincides with the NFL Draft being held in Detroit, highlighting the team's strategic timing.
