Well, let's take one step back. Rutnstrut initially stated that the NFL's "PC" approach would open up athletes to abuse by gold diggers. That claim is manifestly mistaken.
a. If your goal is to live high on the hog, this move costs the arrangement money if it succeeds. If it fails, you get put out on the street.
b. If you are after blackmail, pay me or I go to the authorities, that possibility exists now with the drug and alcohol policy. And it doesn't seem to happen all that often. Think about how easy it it would be to post pictures of a night out drinking and then another of the player driving.
c. The NFL has set a standard (it may change) that the player is off the roster but still collecting a paycheck. So revenge is problematic as well if you really want to hurt the pocketbook even if you are not interested in more payouts.
As for revenge only, the NFL has video and photographs of two incidents and court testimony and a conviction in another. I think you are overestimating the chances a woman can get the domestic abuse charge to stick with the NFL without involving the authorities. Do you expect the women to call Dean Blandino or Troy Vincent and get him suspended without involving the authorities?
At some point you need evidence and that will have to be given to the police.
