I think that Nate Jaquet would be an upgrade over Ogden.
I always liked Denson too, he wasn't big and he wasn't fast but, he always seemed to do well whenever he got a chance to play. I like him as an insurance policy in case Edwards doesn't make it.
I would like to see Cox on our defense too. Again, in a backup role, and for the right price, I think Brian Cox could be another seemingly un-impressive signing, that provides one of those important pieces to the championship puzzle. His fire and his attitude are exactly what you want from a defensive player and every where he goes, that teams defense improves.
