What AB did was pretty disgusting. The worst part is that young people idolize him. The NFL is worried players using weed and getting into trouble but they don't consider at all the effect of this on young people.
The answer is yes it does and not just for the NFL. Karma, God, what ever you want to call it will eventually catch up.
A lot of people already think its ok to sign a contract and not honor it. Some players like Cousins are did it the right way. Whatever they agreed to they honored. Cousins made sure his contract was fully garaunteed. So if he's cut he still gets paid. If players want to argue that the team can cut you and thats unfair then dont sign a contract that says the team can cut you without paying you. What you sign you honor.
AB is a great player but a horrible person and teammate you better believe he has a big bullseye on his back when he plays the teams he disrespected.
