>>11896952I have a couple of theories. Wrestling booking is ever-changing and until your arm is lifted, it's never a certainty. You could be injured in the match and have to call an audible, or you might get a message from the referee to change the finish because the booker decided to go in a different direction, the person you're working with might go into business for themselves. Despite it all being pre-determined there is still a surprising amount of uncertainty to a wrestling match.
