They could do a heck of a lot worse than Okwara and Biadasz with their top two selections... Some combination of Edge and interior OL with their top two picks is my preference as well. A rookie like Okwara could rotate with Ebukam and Matthews as he learns. Biadasz is one of several centers that could come in and start day one.
They will also have #137 (comp) late in the 4th round.
And, of course, expect Snead to move around a decent amount. I wouldn't be surprised at all by a minor move back from #52 to add another pick in the top 130-140 overall.
