The San Francisco 49ers are actively exploring trade options to bolster their defense and receiving corps due to injuries and underperformance this season. Noteworthy potential trades include acquiring Patriots defensive tackle Davon Godchaux, highlighted for his strong run defense and affordable contract, and Panthers' edge rusher Jadeveon Clowney to enhance their defensive rotation. The 49ers are also considering receiver Diontae Johnson to address their depleted receiver lineup, with Titans' Sebastian Joseph-Day as a defensive line candidate for affordable depth. These targeted moves aim to strengthen the 49ers' playoff push in a tightly contested NFC West division.
