That was blatantly premeditated by Gronk. That stuff makes me queasy. Tonight, I was hoping to watch my favorite player from another team, Alvin Kamara, but he got taken out on the first drive with a helmet shot to his head. I don't know if this season is worst than most for injuries, but it feels like it.
Even if you consider the abundance of caution, there does seem to be more injuries happening. Some of these hits seem to be intentional and I don't understand that attitude. Gronk is a seasoned pro, he let himself down badly with that shit. The league needs to take a stand against this sort of thing and start ejecting players. It's sickening.
Very clear head targeting (or any hit) well after the play (as in Gronk's case) should get an immediate ejection. Plus, he should be suspended for the rest of the season for what was the dirtiest play in many years (more dirty than anything ever by Burfict or Suh).
However, immediate ejections for in-play hits are highly problematic and will serious damage the quality of the sport. There are many hard hits in games that are perfectly legal but get unjust flags because of "optics". And often any helmet contact is incidental and due to post contact physics of body movement, despite the hitter clearly aiming for and initially hitting well below the head.
Adding "targeting" or similar immediate ejection rules will be guaranteed to lead to many unjust ejections that determine game outcomes, and an unfair game will lose way more fans than hard hits, which most dedicated fans don't mind. Also, immediate ejections make no one safer than would waiting to carefully review the tape and issue fines and suspensions for later games. If anything, a player hit with a 15 yard penalty is less likely to give another such hit in the same game than they are in their future games.
For example Smith-Schuster's hit last Sunday should probably not even have gotten a flag (but his taunting should have), let alone a suspension or ejection. His suspension is really a PR move related to the overall violence of that game, Shazier's injury that had nothing to do with any penalty, and Schuster's infantile taunting. Had Burfict jumped up and not happened to get a concussion, Schuster wouldn't be suspended, even though resulting injuries should play no role in punishments.
It wasn't even an illegal blindside block by the rule. He came at Burfict directly from the direction that Burfict was moving toward (about the smear the runner), and lowered his body to hit Burfict squarely in the chest, which he did. IOW, it was a front-side block.
The fact that Burfict was staring at the runner rather than looking where he was going doesn't make it dirty and shouldn't make it even a penalty. Any minor contact with Burficts' facemask was due to the physics of his momentum being forced backward by the chest hit, and had nothing to do with his concussion. The NFL is still trying to feed fans lies about concussions by pretending that they are all about hits to the head, when few of them are. They are caused by abrupt reversal of bodily momentum that causes the brain to smack the inside of the skull.
Even with a perfectly clean chest hit an zero contact to Burficts facemask, the reversal of his forward momentum when hit plus a second reversal when his head hit the ground are what caused the concussion. No rule other than making it flag football would stop that, which is why the NFL is trying to con fans that this was a dirty hit to the head.
