The chances of "solid" increase as you go up. It's not that you can't find a good tackle later, but if it were that easy, NOT ONE TEAM would draft an OT in the 1st round.
IF, and that's an IF, you see a guy as Ruben Brown/Ryan Clady quality, you take him. If you think Jered Veldheer is just as good as Trent Williams, then wait. I'm not sure about Bulaga, but he looks like a FOOTBALL player who will battle on every play, NOT take plays off or B word about his contract. He's put up plenty of good tape to justify the selection. I just want a big, nasty gamer. If he's that, we'll all be happy.
