Remember, the players are claiming they never had sex with her, so that wouldn't be possible if they are to be believed. Either they didn't touch her at all (their account) or she was raped (her account). There is no consenual sex defense here that remains credible.
I didn't hear that they had made any statement. I doubt their lawyer would let them make a statement before they have been charged, but I agree that a statement that "nothing occurred" would be inconsistent with physical evidence of rape.
How about she was working her "profession" with several partners before she showed up at the lax party? How about she had consensual sex with several Duke students but not lax team members? Lots of scenarios. It's also possible that, if there was a rape, it was not lax team members but she thought that they were?
