The NFL should have a grandfather clause regarding domestic abuse. Those already in the NFL gets 1 mulligan in order to get it out of their system. Their rage has been building up against their spouse for years probably, and it is only fair that they get to let it out once and for all before being held accountable to any new stringent rules.
Personally, I think everyone in life should get 1 mulligan to use whenever they want no matter what they did wrong. After all, we are all human and no one is perfect. Forgiveness is at the root of all religions.
The NFL is American. And America represents God and the principals of Christianity. Everyone, the NFL, spouses, friends, employers, all should live by the Mulligan Rule of Life, forgive and forget the most grievous trespass any of us will make once in our lives. And believe me, we all will if we haven't already.
What you all say, Cards fans?
