Here's an exaple that illustrates both why Harrison has the rep he has and the failure of the application of the rule at the same time:
Ignore for a minute where Harrison actually hit Massaquoi and look at Massaquoi. Where would you hit him? It's easy to say that 6-inch sliver right around his belt line, but A.) do that at full speed when both of you are moving, and B.) get that low int he first place. It's not easy.
The zero tolerance fines are just as much BS as Harrison's MO.
