According to this, I think it's more likely that Slauson wins the LG job once Woody's gone and Ducasse moves over to RT.
Moore in is his early 30s now. That said, he looks like he should still be strong for a few years. At worst, we have to spend 2 high-ish picks on OLs, and both would be guards, which are not as difficult to find. We're in a very good position with probably the most important unit (secondary?) on our team.
