explore the idea of a rule where a player down with a head injury can be temporarily substituted while being assessed for concussion.
I'd be all for it except that one of the most awful things of soccer - which is even more true in modern soccer - is how much they fake injuries. If there is one element that separated me from watching the game as I used to (I was kinda obsessed), that's the one. Now when I watch a game, it's totally infuriating to me it almost sucks the enjoyment out.
This is to say that if they were to allow such a rule we'd see many temporary headaches on the field.

Allowing 5 substitutes per game will certainly help teams like Liverpool who have a bigger squad. I’d be surprised if they aren’t crowned champions before the end of the month.
I think that soccer should change subs too. I'd go for 2 full substitutions (as it is now); and 4 15-mins substitutions (player can re-enter after 15 minutes, can happen only once per subbed player).
