I do not share the optimism that these trades mean that Orpik is on his way out. Barry Trotz still coaches this team. Both Trotz and MacLellan have gone on record about Orpik's importance to this team. This seems much more like they're blaming the rookies on the defensive issues, and are going to end up pushing Djoos and Bowey out of the lineup.
This. I want to believe that they realize Orpik is killing them and that these moves spell the end of his time in DC, but Trotz gon' Trotz. Djoos and Bowey will sit for these guys and Orpik will still stink up the joint.
