It's important not to get too carried away with the emotional stuff, I read and watched the Power of One and when Morgan Freeman in the movie is all like, "first with the head, and then with the heart", he should have added, "...then with the head again"
To give an example of this, get your binoculars out and train them on the Collingwood huddle at 3/4 time in the 2011 AFL Grand Final, 2:27.06 in the video link below. This is IMO where Collingwood lost the GF, too much "do it for Mick" but not much direction as to how to do it for Mick.
Whereas in the Geelong huddle in comparison, not shown in the video below, but fortunately I had a microphone in there that afternoon, they were all like, "Step 1) get the ball Step 2) kick the ball long and hard into the forward 50 Step 3) Tom Hawkins will mark the ball".
So when the video goes forward about ten seconds this sequence of events plays out, and then about two minutes later again.
