Frye, who was the third stringer in Seattle last season and former starter in Cleveland, is Oakland's fifth quarterback of note. He joins starter JaMarcus Russell and backups Jeff Garcia, Bruce Gradkowski and Andrew Walter.
Just a guess here, but I suspect Oakland envisions Frye being a likely No. 3 quarterback behind Russell and Garcia. Gradkowski has not looked good this offseason and Walter hasn't been attending voluntary camps. Walter didn't get any repetitions during the mandatory camp. Walter will likely be traded or cut as he seeks to revive his career elsewhere.
