Excellent article in the Post Gazette today entitled "The O-line: Changes in store" by Gerry Dulac. I get the paper but I see the article is online so here's the link, if I do it right:
In my opinion, Warmack would make an immediate impact for the better on the Steelers offense in a variety of ways, if we could get him. I don't think you can say that about many other players in this draft. We might see a bunch of teams who pick ahead of the Steelers take a chance on unknown quantities, like QBs. Warmack looks like a sure thing.
