I thought it was just me, but he seems quite flustered. Which is how he coaches when the moments are biggest.
If you think about it, this is the first time he has really faced any serious and sustained criticism. It's not just local media, which is tame, but national media just tearing him apart.
Even after 13 seconds he just shut down questions and everyone disappeared into the off-season. Then it was "we're looking ahead not into the past" and the team won a lot of games in 22 so it wasn't a topic he really ever had to deal with publicly.
Who knows what local Dallas media thinks of Big Mike McCarthy unless you're in Dallas. But every national sports show tears the guy apart along with Dak after every stumble.
These guys care a lot more about their careers and reputation around the league than what the local cheerleaders in the media think.
