Guilty or innocent, he put himself in a VERY bad position with the Nevada woman. He followed that up by putting himself in a VERY bad position with a Georgia woman (the "third" accuser, which allegedly happened second). He followed that up by plying underage women with alcohol (he was the one who got the accuser drunk) and then putting himself in a VERY bad position.
Adam 'Pacman' Jones was never convicted of anything when his 1 year suspension came down, he just had a history of putting himself in VERY bad positions repeatedly (he did ultimately plead guilty on a couple counts, but only after he was suspended). My guess is the Steelers suspend him for a few weeks and try to trade him. If he puts himself in a bad position again, the league whacks him for a year.
