Sometimes you’re standing there and someone comes flying in, so you move your leg out of the way or you go to ground because you’re scared of getting hit. If I leave my leg there so the referee can see it’s a foul, I risk suffering a big injury.
It's a fast-paced game.
If you've ever played the game, at any level, you'll quickly appreciate the fine line of getting injured and going to ground "needlessly".
I disagree with the antics following the plummet but just because someone goes to ground easily does not infer they are looking for a call.
It might be they are simply looking to prevent injury.
