These are the things that are ruining the game more than anything. It is physically not possible for that to not be a flop. Why refs reward guys for that is beyond me.
Im inclined to agree, but why isn't backing down a defender considered charging? It seems like as the defender, if you're getting backed down, you could just stand your ground, keep your feet set, and if the guy knocks you over, shouldn't that be a charge? If not, why not?
