Lloyd Cushenberry and Andre James come to mind. You say fourth rounder, I say 23 million salary. Don't get me wrong, I love that he got Allen. What I will argue is that a good center would be more valuable for Williams' overall development. Problem is, we should have had both. Poles hates to over pay. I simply don't think it would have hurt in this situation.
My whole point is what we've seen in the past. We get Cutler and we complain that had no weapons, we get weapons, then he gets killed because of JMarcus Webb. And so on and so on for Trubisky and Fields.
