The problem is while I'm watching soccer, I am upset when the refs don't give cards as much to clear intentional fouls. Like when a player commits an illegal tackle to stop a fast break. That is an intentional foul , that is no accident. You are purposely knocking the player down.
But, when cards are given and a player is sent off, I feel like the game is over. The other team has won. And if a player happens to recieve a red card , in say, the 15th minute. I wouldn't really want to watch the rest of the game especially if I had paid tickets, I'd feel robbed.
I like the idea of orange cards of putting people in the penalty box. But, I feel like soccer has too much tradition and won't change. Any ideas to even slightly modify it seem radical. But honestly, I like some of the proposals that guy makes. Even though we won't see any of those happen.
