Where does Jordan Addison rank among USC's impact transfers?

With Thursday's huge news that former Pitt wide receiver Jordan Addison will be heading to USC for the 2022 season, the Trojans have now added 18 players via the transfer portal this offseason.

But how important is Addison to USC, really? And where does the wide receiver rank among the Trojans' transfers this offseason in terms of need and potential impact?
