I disagree. Troy Vincent, it turns out, is not "the NFL". The NFL ultimately listened to the coaches and canceled the game--we could see them talking to likely Goodell Dawn Aponte's cell phone in the tunnel.
If McD said "we aren't playing", contrary to the NFL's wishes, they would have had to take the L as a forfeit. About an hour after Hamlin left the stadium, they sorted it out--I.e. the NFL made the right decision. That hour or so really means nothing.
If anything, this reporting makes one guy look really bad---but his opinion did not prevail, obviously. Again....so what? This is more a story for those who are predisposed to dumping on the organization that provides essentially free entertainment that they can't get enough of.
