One rumor I've heard is the Aponte rumor yes. She was reportedly one of his bigger supporters. Another rumor I've heard is that the loss of Mike Dee really hurts Ireland. Dee was one of his biggest supporters and he is no longer with the team. Supposedly the new guy hasn't been impressed with Ireland.
Also you have former players here (admittedly not great players or even good) come out and vent that Ireland is an ass and the players don't like him and reportedly "several" administration members that are more than ready to voice their displeasure with working with Ireland.
I've also heard that Ross was ready to sever ties with him after last year but Carl Peterson, Mike Dee, and Dawn Aponte talked Ross out of it. Well one of those is no longer with the organization, and another had a falling out with Ireland.
