Usually you're right, but I look at FA and I could honestly put together a very decent line this Spring with the exception of a center.
If we signed three starting OL in FA, traded down and took Tyler Badass late in the 1st I'd be a happy boy.
We'll be picking thru reclamation projects and aging veterans in FA regarding the OL position. Teams don't let their OL players go to FA in their prime.
Like i said earlier, we'll sign some band-aids in FA, but it's the draft where we'll find our OL cornerstones for the future.
EDIT: My ideal scenario is to shop for skill positions in FA, and load up on OL at the draft.
