I wanted Wade, but I think that this is a good hire. He is more than capable. I dare say that, if we had the choice between him and Pettine last year, most of us would have chosen Schwartz. Don't get me wrong. I really like Pettine and, knowing what I know after this past year, I would have loved it if he had remained our DC. Nevertheless, Schwartz is a very good hire, and there should be more continuity in the defensive schemes (as opposed to others that we may have hired).
As for O"Neill, the Bills should let the Browns twist in the wind for a week and take their time deciding whether they want to keep him.
