You guys act like flying around like harpoons has always been in the game. It hasnt, it is a product of the helmet and body armor era. If he were wearing a leather belmet or no helmet, think hed hit face to face like that? Of course not.
It isnt a textbook tackle, its a poor tackle. He could have gone low and wrapped up around the waist and or legs. That would have been a textbook tackle.
If that receiver hadnt been otherwise occupied due to the pass taking him out of stride, he would have run right through that.
The rules are the rules. No hitting to the head and neck at least on a defenseless player. Id be all for it changing to now intentional hits to the head.
Go low instead of trying to knock them out. The players will appreciate it when less of them are invalids getting fed jello in a nursing home at age 50 dus to head injuries.
