Here's my deal....
No one is above reproach in my opinion. In Hardy's case, the justice system ran its course and the charges were dropped. While I don't condone ANYTHING he did, there were also circumstances on the other side that did not make the situation an easier.
All that said, he'll serve his suspension and have a shot to prove he's worth it on the field and off. From what I've read, the Cowboys aren't out any guaranteed money. If he screws up again, they can say "see ya" without any financial repercussions.
Football-wise, I love it. It fills a huge need that we can now look to fill other needs with top draft picks (RB, DB, DT).
Such is life, if you have talent and/or useful skills people are far more inclined to forgive you. Which is sad - because we're all sinners and none of us deserve forgiveness but we get it anyways.
