Pass, rush, yards, interception, fumble, penalty, tackle, helmet, touchdown
If you hit your head on something, the helmet will spread and soak up some of the energy of the hit, reducing your risk of head injury. If you don't hit your head, the helmet won't do anything. In extremely rare cases, the helmet will snag on something and yank on your head/neck.
In the NFL, the play would be a fumble as a player must be 'downed by contact' for the play to be whistled dead. If there was no contact causing the player to hit the ground the play is still active. In college football, the play would be dead as there is no 'downed by contact' rule and once the player is on the ground the play is whistled dead.
fumble is when you use one hand to do something and not the other
It means, I'm still sad ,when my mom hit me with a helmet.
A helmet lead hit to the side of an opponents helmet (their earhole).
Protec helmets are mainly intended for skating/skateboarding. The main design difference between a skate and a bike helmet is that the bike helmet is designed to take one big hit and then be discarded, while skate helmets can take several smaller hits and still be OK to use. If you were to take a really hard fall, then a bike helmet will protect more than a skate helmet, they can soak up more energy. Still, the "wrong" helmet will offer more protection than no helmet.
The Fumble happened in 1987.
Yes, a fumble is a fumble, the cause doesn't matter.
No.
a fumble that cannot be advanced by the kicking team Under current NFL rules, whether the ball hits a receiver in the helmet or not, is a non-factor. You can catch the ball off of your head, someone else's head, etc. So long as the ball never touches the ground. That said, it's illegal for a pass to hit an ineligible receiver first (an offensive lineman for example) in any way.
Fumble - band - was created in 1967.
