I say discipline/sanction them for ALL of their crimes! These people are paid SO much money, that they should behave if they want to continue to keep getting all of that money. The price of fame and celebrity-ism.
Of course, the more I think about it, the more I realize that we would lose probably 25-50% of all professional athletes at one point or another for some period of time or financial penalty.
Professional athletes have a very broad fan base. From the young and impressionable, to the elderly. I believe they should be held accountable to a moral and ethical standard. I've been a Steeler's fan for better than thirty years. Big Ben Rapesburger is an embarrassment, and has tainted the team I like to watch.
