The San Francisco 49ers are in a complex trade situation involving wide receiver Brandon Aiyuk, who has requested a trade after failing to secure a contract extension. The Pittsburgh Steelers have emerged as a primary suitor, offering Aiyuk a $28 million annual deal, but have not met the 49ers' trade demands, which include draft picks and possibly another wide receiver. Amid the ongoing trade talks, the 49ers have signed veteran receiver Robbie Chosen to a one-year deal. Other teams like the New England Patriots and Cleveland Browns have also shown interest, but Aiyuk has turned down offers from them. With the NFL season rapidly approaching, it remains uncertain whether a deal will be finalized soon.
