Ben Roethlisberger was likely the victim of a false rape claim.
You may not like him as a person -- he certainly behaved like the stereotypical pig the night he allegedly rape a college woman -- and you might not like the Pittsburgh Steelers. But let's stay on point here. In all likelihood, Roethlisberger was the victim of a false rape claim.
Roethlisberger accuser's various statements to police suggest the evolving narrative of a woman groping for victimhood. In chronological order: The accuser's (1) "No" in response to a question about whether she was raped, and her "I'm not sure" if she and Roethlisberger even had sex, were later transformed into (2) the accuser claiming she told Ben "I don't know if this is a good idea" before they had sex, which was later transformed into (3) the accuser claiming she told Ben "no, this is not OK" before they had sex, which was later transformed into (4) "No. This is not right. I do not agree to this," and a claim that they did have sex, and that he penetrated her.
It is fair to say that the accuser's memory would have been best in the time right after the alleged incident. Yet she went from "I'm not sure" if we even had sex immediately after the alleged incident, to I told him "I do not agree" to have sex, but they had it anyway. This suggests a credibility gap that would be difficult to bridge in any case, and that's almost certainly why charges were not brough against the quarterback.
Roethlisberger seems to have recovered nicely. Although he was suspended for four games earlier in the season, he is two wins away from another Super Bowl ring. "His achievements have been such that in only his seventh NFL season, at age 28, there is perfectly legitimate talk about Hall of Fame enshrinement five years after his retirement." See here.
