Why would the League force Jones to sell? He hasnt been found guilty of assaulting her yet. Plus, the girl has a questionable past of accusing people of assault already. Hell, even her low Rent Ambulance chasing Lawyer / Pimp has his own domestic assult case pending in an actual court of Law.
Jones hasnt used any racial language in public and he hasnt had videos of him hitting women surface yet.
The only thing Jerry Jones has been proven guilty of "assaulting" so far is the football knowledge of both the NFL and Dallas Cowboys fan base's. And there is No law against that. Former St Louis / Arizona Cardinals owner Bill Bidwell is proof of that.
