I'm not against drafting O-Line in the 1st, but I do think there will be some good OG options in the early/mid 2nd round. Regardless of where they draft OL, I don't think you really want to count on starting more than 1 or maybe 2 rookies on the OL (I think you would still consider Barrett Jones a rookie at this point).
I don't think Jake Long will be back until the middle of the season. If Saffold gets offered more than they're willing to pay, I don't think that spending two 1sts on OLine solves the OL problems for 2014. They would at least need to bring in someone on the J'Marcus Webb (Vikings) level to hold down the fort until Jake gets back and/or you can get a couple rookies integrated into the pro game.
Honestly, I'm not categorically against spending the first three picks on offensive line (depending on how FA shakes out); I want an influx of talented youth at the position. I just don't think that rookies are an immediate answer to the problem.
The only thing I absolutely do not want them to do is draft Jake Matthews 2nd overall. I just view that as a complete waste of value. I don't think you can say that he's a pointedly better prospect than Robinson, Ogbuehi, Kouandjio, Lewan, or Erving. Even if they can't get a huge package for a QB, someone will pay you for Clowney (I'm still on board with drafting Clowney by the way).
