Not a lawyer- but things I can think of that could be used to support her side of the story-
She isn't alleging that they held her down and forced themselves on her- rather a combination of her both being too drunk to consent, and not wanting to consent but being "directed, manipulated and intimidated into remaining,". So what could that evidence be? Anything that corroborates her hesitance/desire to stop and the players recognizing it and pushing her to continue.
The "consent" video itself could speak to her intoxication/capacity at the time, as well potential duress. The very existence of the second video could be used to infer that something happened in that hour that gave the players concern and reason to want it- such as her wanting to stop.
Texts between players showing their observations of her behavior/ their misgivings at the time
Possible videos between the two that are publicly known of
Bartender/Uber driver witness accounts of her level of intoxication
The statements of the players themselves
Security footage of the golf clubs going into the room
Etc etc.
