Has there been any offer or interest in an interior lineman so far this fa season? The only thing I've heard of is the offer to Buluga at ROT. Almost seems like at this point they are not looking for a starter in the interior.
If I recall correctly Williams' main problem was pass protection but he was decent at run blocking. I guess they could still cut him, but why wouldn't they have done it already if he's not in their plans? And these questions aren't specifically to you, just thinking out loud here.
