You hear this sort of thing in a lot of sports though. Squeezing the stick too hard in hockey and trying to do everything yourself. I think sticking to the game plan is what they mean instead of trying to be a hero and winning the game all on your own.
I had to go back to see who made the post (polar bear). Hence, I don't have the foggiest idea what you're talking about. I've never referenced him in any post ever before.
