You never have too many CBs...and with our lack of pressure on opposing QBs, we need all the cover guys we can find, along with a FS.
I'd address OL with at least one position in free agency and another 1-2 in the draft.
But the bottom line is you can't just say you're going to draft a bunch of Olinemen and improve the line...if the players aren't there in the draft, you don't reach because you may not be getting a starting lineman anyway.
IN the draft, it's still BPA unless you can move around to get the lineman you want.
