Sadly I feel like its an inevitability that this happens in the NFL, and relatively soon.
But I'm not sure it will slow the game down. I know that football is struggling at the youth level, and have gone to flag football versions in many communities. But there is just no way to avoid sudden and tragic injuries in youth sports. they are more "freak" than anything one would consider a norm. We have had a couple tragic paralyzations here in MN over the last couple years in hockey, and while there is an immediate call to take contact from the game, it typically fades away.
sad for the boys family.
