I imagine it's a combination of many of the points mentioned
-Perhaps there is an element of taking it a little easier at home because it's our home and so we think their our points to lose
-The top teams are more disciplined and defensive against us when they visit, the lower teams come to us without fear since they can walk away without shame at losing
-The defensiveness/fearlessness makes the crowd get uneasy if we struggle to break them down/score
-The unease of the crowd seeps into the team who then rush and/or hesitate
-Then when we're on a run of poor results, gus and the team start second guessing, becoming more defensive, or take too many risks
