I think it’s a sign of weakness that you either allow yourself to get so worked up - or you really think it gives you an advantage.
Same as teams going on to a pitch pumped up and ready for war. I’m thinking of Pillar.
The thing with JG is that he’s very controlled and cool…and you see that in the play. No one panics. If you get caught up in stuff, there’s a chance you’ll be hauled aside.
It’s what the good teams do. They stick to the process and try not to get caught up in the emoition
