You shouldn't expect anything out of an athlete other than superior on-field performance. These guys are either in a gym or on Twitter. When your connection to humanity is in the form of exhaustive vomiting and hash tags, there's a lot that's lost in translation. If you have kids, make sure they never act like professional athletes. Otherwise, you'll have a volatile Little Leaguer that's addicted to pain killers, arguing strikes, and sexting.
No one really expects athletes to be role models.
