Yes. I feel like any time Mac is in front of the media he is very PC. He says the right things, uses some cliches and maintains a positive outlook."non-PC"?
I can't say for certain, but based on the way I've seen him react on the field, at times, to refs, players, and coaches on his staff, I don't think that's truly how he's like behind closed doors.
I wish he'd be more like Patrick Roy and less like John Fox in his dealings with the media.
