I think Martinez is rattled by all the hype. The ESPN camera crew was all over him before the game. Maybe he has issues handling the spotlight? Believe I saw this mentioned in an article online too. Personally, I'm not for young kids being interviewed so much by media personnel. They don't tell the media much different than what the coaches do. I understand it, but I don't like it.
Some of the players could benefit from a social media blackout, too. Not going to name names but some players talk the talk a bit much on the internet. I'm in my mid 30's and grew up initially without social media, the internet, etc. Guess I prefer guys just keep their mouth shut, go to work, and let their talking happen on the football field.
