I think 2012 was much closer to an accurate representation of our line than 2013 was. So many damn injuries in 2013, including guys who played hurt and played like crap all year long.
Recent history has shown that OL are over-drafted and weapons tend to slide on draft day. You never see guys like Joe Thomas, Russell Okung or Trent Williams sliding into the twenties. But it seems like almost every year there's a Percy Harvin, a Dez Bryant, a Demaryius Thomas, a Roddy White, a DeAndre Hopkins, a Cordarelle Patterson... not to mention that the top rated TE prospects have usually gone in the 20-40 range. There's also a very long list of star NFL WRs who were taken in the 2nd round.
Though I do think Seattle needs to become more stout inside on the OL, the reality is that we just aren't picking high enough to fix that problem without a ton of luck being involved. On the flipside, our team has a very real need for weapons and history suggests that Seattle could walk out of the first round with a potential star in that area.
In the end, it depends on how Seattle grades their own OL, how they grade their own WRs, and how they grade individual players in the draft. Drafting OL in the first round is definitely not out of the question, though I suspect Seattle will situate themselves so that they are not pigeonholed into drafting a certain area early. But as things stand right now (assuming Breno stays), I think the biggest area of upgrade will be at WR or TE, unless Seattle just really hates this year's crop of WR/TE for some reason.
