The club is linked to several potential trade targets to cushion the pass rush: Trey Hendrickson, Jaelen Phillips, Micheal Clemons, Arden Key, Tyree Wilson and Dondrea Tillman. Each option comes with distinct cost, contract status and fit, from veteran rentals to high-upside youngsters. San Francisco is weighing draft capital versus immediate impact as the trade deadline nears.
