Perhaps it's joke, but TBH, I would feel kinda "odd" singing that song at halftime, just because it's a hymn. I might do more of a "Jesus in the temple with the money changers" thing.

Not saying you have to do a Tyler Batty, and blow out obscenities, but being authentic and having integrity in the moment, is just as correct of a principle as being emotionally in control. In fact, I think authenticity is a key part of integrity, and having integrity is a much higher principle than "not swearing" IMO. That makes me be less shocked, and less judgemental about Batty's apparent tirade. And the defense mostly did their job in the second half, which was a noble response for their teammates. Do your part for your teammates, that is a principle with more import than whether or not you swear in the locker room.
