Thankfully, events like this are rare, but allowing runners to smash head first into tacklers is a recipe for concussions. It only happens because we enjoy it, but we liked to watch defenders wiping receivers out at one time, too.I doubt you'll see anything. This is like a once in a generation type thing. You may go 40-50 years and not see it happen again, with no changes to anything. This isn't close to like head trauma being routinely caused or specific types of blocks or hits that somewhat frequently cause injuries.
This is basically like lightning strike level of activity. It's not preventable. The only recourse is to have the best possible reactionary procedures to it. And generally speaking, the NFL and those teams are being herald for how they handled it. Super quick response time, super quick actionable items were taken by medical personnel. Was apparently diagnosed very quickly in a situation where a normal person probably wouldn't notice an issue like this immediately.
