I go back and forth on this whole safety issue. As someone who worked with individuals with acquired brain injuries for almost 2 decades, I saw first hand what can happen from unchecked or incorrectly used safety precautions. Accidents are one thing; falling from a height, being involved in a vehicle accident, etc...Incorrect harnessing, not having restraints or not using them correctly....in an otherwise safe situation that suddenly becomes unsafe. All of us take the same risk driving a car or climbing a ladder e.g.
But, there are certain professions where, although it's not *expected*, it is a real possibility that a certain injury can happen. Sports, law enforcement, aviation, etc...when you do things with higher risks, the negative results are, obviously, a much higher likelihood. After watching a clip from a boxing match the other day where a fighter was literally knocked into a coma, and is currently in critical condition, I'm baffled at how certain sports move away from such scrutiny (from the participants, anyway)...I mean, a lot of people think boxing and other pugelist sports are barbaric and shouldnt even be "sport"...thats not an argument for here. You cant tell someone to not hit someone too hard, when the entire task is to literally knock them out (iow, the GOAL of boxing is to cause a concussion).
The goal of football is NOT (contrary to popular belief) to knock the other guy out. Its to tackle him. Period. So while I totally agree that the call against Walker was complete junk and should have been reviewed, I can't say that I have a problem with calling a personal foul on almost any hit where the defender goes high on the ball carrier (though thats not what Walker did by any stretch). For instance, I saw alot of people, regardless of team affiliation, claiming they thought the penalized hit that concussed Mason Rudolph the other week was a bad call. No, it wasn't. When you're trying to TACKLE someone, you want to get low on the body, take away the legs, be a lower center of gravity than the other guy. Regardless of how insignificant the hit seemed, the issue was that it was a HIT. Not a tackle. "Wow what a HIT," - not "wow, what a really good tackle." - Earl Thomas did not tackle Mason Rudolph, he hit him. Thats a penalty. This was actually an excellent example of the rule being enforced correctly.
Look at rugby. A rough sport. Where tackling is again key. They wear minimal padding, if any. And some dont even wear scrum hats. Yet, they have an instance of only .5 more concussions per 1000 AE that American football. IOW, out of every 1000 times any rugby player plays a game or practices there are 3 instances of concussion. For every 1000 AE for American football its 2.5. How can that be so? Because watch rugby, its a game of close contact, scrums, form tackling and VERY few hits or sticks. Basically, rugby players are actually trying to tackle the ball carrier, American footballers are trying to hit them.
I agree that the game happens fast, and I agree I wouldn't want to be a ref trying to keep up with the pace. The baloney hands to the face calls against Trey Flowers were flat out horrible calls. The call on Walker was a bad call, but understandably flagged at first...but should have been reviewed. In fact, the ONE call that Detroit actually COULD have reviewed, the non pass interference call to Marvin Jones, was inexplicably left unchallenged.
But back to the issue on safety, the problem is not solely on the refs for throwing too many flags, its for way too many players going for the hit, going for the knockout punch. The fans want to see it. The players like to celebrate it. But the refs are going to penalize it. And rightfully so. Stop trying to knock the other guy out...and become a boxer if thats your goal.
