I'm not sure if it should have been an illegal hit, and I don't think a players history should be a deciding factor in whether to consider something legal or illegal. It is either legal or not. If not, sure then look at history to determine punishment.
Many times I've seen a WR running a slant or offenses doing "RUB" routes, and a DB shoulder chuck them and knock them off their feet preventing them from being able to finish the route. That would be illegal under this rule. Offenses are going to adjust plays to you have guys like Gronk crossing shallow where they will basically be untouchable. All defenders are going to be able to do is tackle after the catch, not stop it from happening.
