And it only slightly changes my opinion. He certainly wasn't ranting and raving, which he normally does, in that press conference. But he made sure to point out that he thought there was another pass interference earlier. And then he went back in the middle of the press conference in answering a totally unrelated question, he counters back to reiterate that he thought the refs didn't do their job.
He comes off as a whiney baby, just not his typical obnoxious whiney baby self.
