So the NFL wants to fine teams that don't follow the concussion protocols. If I were the NFLPA I wouldn't fall for this. Just another power grab by Roger Goodell.
I have a better suggestion. If a team obviously doesn't follow the concussion protocols (like with what happened to Case Keenum earlier in the season) and a three doctor panel agrees - then the affected player gets his entire contract guaranteed. If a team suddenly feels like there could be salary cap implications in treating a player's health like a disposable commodity - then you would suddenly see a sharp change in how things are handled. Teams would be instantly erring on the side of caution (as they should anyway).
So let it be written so let it be done.
