That doesn’t qualify at all. The player had already left his feet to initiate the tackle. Pretty garden variety “diving tackle”.

They’re trying to eliminate plays where the defender grabs hold, then leaves his feet to drag the player to the ground. I see a massive difference between the two.

Again, I just don’t see this is as particularly tough to identify.

then he "goes weightless" (per the wording of the rule) and lands on the back of the players legs (and then rolls off).

You trust these refs to get this correct, on a bang-bang play like that? When they can't even call blatant holding penalties? When they can't even properly spot the ball?

I most certainly do not. Now, do I think that right now they would throw the flag for it? No, I think that they'll let the league enforce via fines. But then, what's the purpose for having rules to begin with? I suppose we could ask that about damn near any penalty now, to be fair.

which have been taught as a way to "take the head out of the game" (Hawk tackling by Pete Carrol basically teaches the player to go to the side and use their momentum to the ground to take the player down), I pretty much agree with you.

Now, you pretty much can't touch the qb at all (and in the case of a guy like Mahomes, you can't breathe on him and his OL is allowed to hold every play), you can't hit wr's high over the middle, you can't tackle from the side while leaving your feet (causing more head on collisions), etc.

They create these rules to placate the people who hate football and think it's too dangerous and to cover their ass for potential lawsuits.
