Goodell doesn't make the rules, moron. The various owners' committees do. Harrison's been fined for flagrantly violating a rule, leading with his head, spearing, to make tackles. It's been a rule for more than 50 years. If he had ever learned to tackle right, instead of show boating, he wouldn't have a problem.
I don't understand how a pussy like you, who never played any sport, is in any position to call NFL play "soft". Never took a spear to the lower back, did you? Maybe you'd be more happy in the WWE section.
