Think there is but imo that's for seasoned teams that have runs on the board Sydney have been renowned for it in the past mainly through preseason not young developing sides like Carlton .Its all upstairs. Subconsciously there are various gears that elite athletes have. Look at the increase in intensity in the finals V home and away matches. The difference between grand final and other finals. Not such a huge leap to see that there is a difference between preseason and H &A matches.
But is there a switch, I am not sure there is- other than a subconscious one
In Carlton sides imo the switch has flicked on and off way too often over the past 15 odd years .
