Even if the NFL could win in an appeal, I think they may want to and eventually drop this. The reason comes back to defamation of character. The NFL labeled him as a domestic abuser, which was their biggest mistake. If they had just stuck with conduct detrimental to the league and not labeled him as a domestic abuser, we probably wouldn't be in this situation now.
The label is already out there, Pandora's box has been opened and the horses have made their escape. It's the ole case of...they may win the legal fight, but will surely lose the civil case. If the NFL is willing to take on the civil case and the consequences of it, so be it.
Money talks, in the end maybe a settlement is reached? If I was Zeke though, the civil suit wouldn't be just against the league, I would be naming individuals involved in the process, who are for me personally, the ones that really matter....Roger and Lisa
