This is just a symptom of a larger problem that the NFL needs to address which includes players intentional laying on opponents, raking across them, landing on their lower legs, etc when it is not necessary. If they would throw the flag sooner they would discourage more egregious behavior late like this Suh incident.
No, Suh is in a class by himself.
Matter of degree IS important. Is Suh the only one? No - but he’s way way way out in front of everybody else.
