My Hypothesis—davidbdale

1. concussions in football
2. concussions and helmet design in NFL football
3. the effect of improved helmet design on the number of concussions suffered by players in NFL games
4. Helmet designs that act like shock absorbers to reduce the impact of helmet-to-helmet blows will reduce the number of concussions suffered by players in NFL games.
5. Eliminating helmet-to-helmet blows would radically reduce the number of concussions suffered by players in NFL games.
6. Eliminating helmets from NFL games would reduce concussions more than helmet improvements by making players very reluctant to engage in the most dangerous plays.
