The headline (http://blogs.tennessean.com/titans/2012/10/01/munchak-agrees-with-harris-he-had-a-good-day/) in the local paper is "Munchak agrees with Harris: He had a good day."
It looks like Munchak is following Jeff Fisher's formula of "relating to players."
Maybe i'm missing something but even in the pro-black casteNFL a player who makes some big plays against a team is given begruding respect. For a OL to brag about locking someone down who had two sacks, some tackles, and a fumble recovery, is a bit much. Of course the OL wins most of the battles, but it's the big plays, sacks and turnovers that make the difference. Needless to say I've never heard a White OL insinuate that he had a good day if the defender in front of him put up those numbers. I am surprised the coach didn't tell his guy to shut up. I'd expect that as a fan.
