Every game has one and that one is the worst of all of them
he tackled incorrectly by using the crown of his helmet and what they are trying to get kids not to do.
1) it's usually worse on the player getting tackled and can cause worse injuries (not so much here....the player got tackled in the chest)
2) it's bad for players to tackle with the crown as it can cause injuries to the head/neck to the player doing the tackling
football has a big problem with head/neck injuries and concussions. they are trying to prove they are doing something to stem these injuries by instituting these rules, even if in some cases they go beyond what really makes sense.
