Ever since they have started talking about an "independent spotter" all i can think is the massive unintended consequences that could arise. You have violent hitting on every play. Now they're going to allow some yahoo up in a booth to watch a screen and determine who has to leave a game? No way, that should be determined by a doctor. They blew it with Tua, but this is a massive overreaction. You're going to have some big playoff game or a Super Bowl where Mahomes, Allen, Brady, Hurts, etc. are going to be pulled from a game because some spotter *thinks* the guy looks shaky. How do we even know that the spotter at the game yesterday didn't have money on the Jets? Ok Teddy, take a seat.
There should be video evidence for starters AND the player should be checked by a real doctor and cleared to come back in the game if he's deemed to be ok.
