They need to start issuing massive fines and multi game suspensions for provable air particle falls. Faking an injury to gain a competitive advantage is the lowest form of sportsmanship.
I had a long conversation with a Turkish guy who was earnestly trying to convince me that the fake injuries were the best part of soccer.
His argument was that "unlike Americans, Europeans would use any method that isn't technically breaking the rule to win and that's what's so fun."
"See it isn't technically breaking the rules because you can't prove they aren't really hurt!"
"Of course they aren't really hurt that's how smart they are."
How clever. To dramatically grab your knee to avoid playing a game that is your entire reason for being there in an often vain attempt to underhandedly game the system.
