My theory is that jill farren phelps recommended Muhney be fired to Sony & CBS for storyline purposes in November. Since JFP has been known to fire popular fan faves, she goes to Sony & CBS who takes the hit for her. Rather than take the blame, she takes the cowardice way out. She claims Sony & CBS made the decision since Adam hit & killed Delia. Once she made the decision, there was little else to do but get rid of Adam if not temporarily. JFP probably has an FOJ to take over the role. That's just my theory! While mm has a big mouth, I believe JFP wanted to silence him & his contract cycle ended too.
