This also stood out to me.
Concerned that linking football to brain damage would be bad for its bottom line, the NFL sponsored and created bogus scientific papers claiming that concussions in professional football "are not serious injuries" and that "many [concussed] players can be safely allowed to return to play on the day of injury”; as recently as last year, Goodell still refused to publicly acknowledge that football-induced concussions could produce long-term neurological harm.
We all know now that Goodell has done a complete reversal. So much so, he now will have spotters looking for concussion type injuries that may be missed by the team. You know, like Edelman in the SB. I'm sure Goodell is kicking himself for not thinking of it sooner. Those spotters (probably former Jets employees) would have had the authority to pull Edelman off the field thus making it more difficult for the Patriots to win the game. It's probably why Goodell created it.
