All good points. I suppose second opinions wouldn't be needed under my proposal - and the player would lose some freedom in selecting their own doctor. For what it's worth, I'm not sure who picks up the cost for the second opinion - the player, the team or somebody's insurance. I imagine one of you knows (probably Guido).

Your blog does make me think about a guy like Winston and how they have similar situations. Tua had a game injury (Sunday) and then played his next game (Thursday). It’s possible his Thursday injury was related to his Sunday hit, maybe not. But we know he played with having an issue in the previous game.

Well, Winston has a known injury to his vertebra. If he gets hit in the same area and gets hurt worse aren’t the Saints guilty of the same thing Miami was? How about Kamara? It’s an interesting point of discussion. Following that line of thinking, any player playing at not 100% is taking a similar risk. Obviously head/spinal injuries are in a slightly different class though.
