“Among the top names available in free agency are tackles Javon Hargrave, Dre’Mont Jones and David Onyemata and ends Yannick Ngakoue, Jadeveon Clowney and Marcus Davenport. More cost-effective options who profile similar to past Niners additions include tackle Sheldon Rankins, end Ogbonnia Okoronkwo or even a reunion with do-everything lineman Arden Key......Should the Niners look to spend on a cheaper replacement if McGlinchey leaves, some of the other tackle options are Kaleb McGary, Jawaan Taylor and Isaiah Wynn. If they look to invest in the secondary, a couple names to watch are cornerback Cameron Sutton and safety C.J. Gardner-Johnson.
