I don't think it means anything, other than what it means. Barks may be gone too, and it doesn't mean that we will pick OL in the 1st round, or more succinctly, at #10.
Rhaney's Pro Day numbers were better than any Center in this draft. We could make a run at Wisniewski. Jake, already lost his job, and is rehabbing. We could probably find a starting RT in the 3rd, and a starting Guard in the 2nd, or the 3rd.
Washington, Person, and Jones are in the wings, waiting for their chance.
This is good for the Rams, this is a good move.
