As for precedence being set...not really. Goodell has said that a big part of this punishment was because of multiple violations without the team really showing any kind of remorse. So yes if another team continues to ignore the rules then I can see precedence come into play but a team that has been good for quite some time and gets caught doing something they are not going to get this harsh of a punishment.
Think about that the next time you get a speeding ticket. You had one in 1998 and you got another in 2016. You certainly didn't show any remorse......that'll be 5 years in state prison.
