Banging drunk college girls in the bathroom may a goal of some but rape shouldn't be - and separating an extremely drunk girl from her friends that are openly trying to protect her and then cornering, having sex with her, and using your NFL status to put pressure on her because she is traumatized and seeking justice because she doesn't know the EXACT details of what happened - only that she was taken advantage in the most personal of way, so she drops the case - that's rape and, legally, he got away with it.
He got away with it because there is a really blurry line of personal responsibility/use of judgment when alcohol is involved and a lack of solid evidence that the girl said no.
But basically he has caused negative attention upon the NFL too many times. Getting rid of him may be the best thing that ever happened to the Steelers - and I hate to say that since I am not a Steelers fan but there is much more/better talent out there without all that Springer drama and he just opened up an opportunity for them to better their team.
Good riddance, Mr. Roethlisberger, may your example of douchebaggery and overindulgence serve as a lesson to others. Personal responsibility is a 24 hour a day nag, it doesn't go away just because you have a few drinks, money to burn, and noteworthy talent.
