The players voted on the leadership council. Jon Martin voted for Richie. Mike Pouncey denies that anyone told them to 'toughen up' Martin. Lydon Murtha said that the entire unit was asked to socialize him into the group and, to paraphrase, become friends with him.
Wait until the NFL investigation has finished and then call for someone's head. I'm pretty sure Jeff Ireland is burnt toast and Joe Philbin may be out on his ass, too. But from a personal standpoint, I find it hard to believe that what was going on in that locker room was something horribly monstrous and different from what happens in every other NFL locker room based on all of the information I have available.
As for Joe Philbin specifically, Hard Knocks has hours and hours and hours and hours of footage of Joe interacting with coaches, players, and front office people. I think it's very likely the NFL investigators will have access to that footage, and IMO that will provide a much clearer picture of whether Joe was a horrible villain who 'ordered the code red' or if this really is what I initially thought it was, a situation in which a totally dysfunctional relationship between two idiots takes down an entire organization.
