Another rule change idea from yours truly: When a player goes down like he has been shot, rolls on the pitch, punching the grass in agony , the ref let's him do his thing . But if he starts running like a cheetah after he gets the foul call he desperately needed, the ref stops the game, pulls him aside and says " You know, just a minute ago you were in agony, rolling on the pitch, punching the grass. I believed you, and your health is the most important thing in the world for all of us. So , now go sit on your bench for 15 minutes while your club physician keeps an eye on you. If you are good in 15 minutes, you can come back in. Your team will be a man short for 15 minutes but that is a risk we are all willing to take for your health, which is more important than any silly game"
Fair?
