Assuming that, with whatever limited funds the Rams have to spend in FA this off-season, they pursue help for the interior OL, the Rams will likely look for a deep threat in the draft.

However, I think that John Ross might be another option. Due to his injury history and bust status, I suspect that he'll likely have to sign somewhere for close to the minimum with a one-year "prove it" deal. And as he's originally from Long Beach, the Rams may be an attractive place for him to consider as his primary calling card is speed (4.22). Let him compete with a rookie drafted for the same.
