Honestly I'm not shifting all blame to Ireland (Michael Egnew was reportedly a Joe Philbin request) but I do think that it's become obvious that there was a HUGE disconnect on players. Some on Philbin, some on Ireland. There are rumors on both and there is probably enough truth to go along with it.
My belief has always been that a GM should be able to work with his scouts, the head coach, and all the assistant coaches to pick players. I don't really think Ireland quite understood what type of players Joe's staff wanted.
