It probably was all Loria, but he hitched his wagon to him. I can't say that I blame him - he had a dream job.
He should have walked away with a little bit of dignity that he had, rather than shitting on everybody and everything he ever came in contact with during his Marlins tenure.
He could go away, and be forgotten about a couple of years. Instead, he has chosen to be an attention whore. Nobody cared what he had to say when he was in his previous position - they certainly don't care now.
He tremendously overvalues his worth to the game.
