I've never understood how this can happen to competitive sportspeople! Over-arousal sure, but not taking it seriously...I don't get it!
It's a massive final in front of 50+ thousand screaming fans...if you can't rock up for that something is badly wrong!!
Certainly for a final, I agree, there should be no way you're not coming out to play. But we play a sport where if you're a few percent off your game, you're in trouble. If the players go in even half subconsciously feeling like they've got this game won before it starts, we could be in trouble.
