No I don't think it would, even if was found innocent at some point down the line, that doesn't mean the girl has done anything wrong. She woke up alone, unclothed in a hotel room an couldn't remember how she had got there, by any reasonable person this is cause for concern and as far as I know she has told the truth throughout, it wasn't the girl who convicted Evans of rape it was a jury and thus his treatment of her would still wrong even if overturned.
To suggest otherwise sets a dangerous precedent for future rape victims coming forward.
If Evans ever was proven innocent surely his anger should be directed at the justice system which found him guilty in the first place and not at the girl.
