Let's be real. For PR reasons, NFL would rather over-punish than fairly punish. They started this investigation with no intention of being fair and saw this as PR opportunity to come down hard on a big name player. They are coming off a season where they took a hit in the ratings and in the media and want recover as soon as possible. 1st step, proving to the social-media justice warriors that they tough on domestic violence.
Sucks for Zeke, but he shouldn't have put himself in this situation, and he'll learn. Not 1 person has anything negative to say about his personality other than needing to be more mature. Having said that it's sad that the concept of punishment fitting the crime has gone out the window. NFL personal conduct policy is pretty much just an angry mob with pitch-forks.
