Nice, I think we'll have a really good idea of where they'll be going in the first based on what they do in free agency.
If they let Biadasz go you may as well earmark our first for a center, there's a chance they wait it out until the 2nd but I think it'd be at least 75% that they go center in round 1. Conversely, if they re-sign Biadasz and let both Gilmore/Lewis walk I think there's a decent chance they go CB (unfortunately), especially if Wiggins or McKinstry are there.
My hope is either OL or DL in the first unless a clear BPA/Lamb-type situation happens, but I could easily see them going CB given the depth in the first and how much Zimmer loves taking CB's high.
