I listened to Silverstein say that O'Donnell is everything that Bojo was not. He is consistent, doesn't out kick his coverage, kicks well in the cold, and is a really good holder on kicks. I liked Bojo but he really did fall from the heavens to the ground in the later part of the season. You can't have bad special teams when going for championships. He'll be good somewhere once he shakes out the consistency issues, but is not the right fit for the Packers right now.
O'Donnell should provide stability, which is what this team needs more than it needs.
