I suppose, but that process has already occurred (albeit flawed), and hes been found guilty. I don't know a damn thing about law but I feel like the CBA (and its powers) are ironclad.
So now Dallas season is 1/3 over and already circling the drain with the Eagles divisional lead, EE still has to eat 6 games in there somewhere, and the defense smells of elderberries. IMO, I don't see the playoffs in Dallas future so he needs to serve the suspension this season so it doesn't bleed over to next season.
