I would draft at least one offensive lineman every year no matter what.  Having young developing offensive linemen is that important.  

But for this year, I would also say, good receivers can be just as beneficial to pass protection as offensive linemen are.  Young QBs have a tendency to hold the ball too long when they can't find an open receiver.  Especially rookie QBs who are used to the college version of "open," which is open by 2 yards or more, vs the NFL version of "open," which is open by a foot.  Young QBs need WRs and TEs who can give him obvious targets and get the ball out of his hands.  

We've all seen young QBs get sacked even though they have good pass protection, and we've all seen veteran QBs who are hard to sack because they get the ball out quickly.

So if we sign a top quality offensive lineman in free agency, then with our next few picks in the first and second round, I would look for weapons as well as offensive linemen.  Because it takes all 11 guys to make an effective offense, and all the pass protection in the world won't do any good if the QB doesn't get rid of the ball.
