I dunno, i think OmarSekou is on point here. Some type of monetary fine is what it will take to curtail this acting.
Officialls aren't calling these flops for the hell of it, they're doing it because players have become so adept at waiting for the right time of game and the right contact and then exaggerating it to perfection. Most flops are very quick and officialls generally don't have the best vantage point to discern just what exactly happened.
Let the refs continue to call it how they see it, and, if a league review team decides a player went out of his way to "hurt the integrity of the match" by flopping, then send him a warning followed by monetary fines.
As you say: "most flops are very quick and officials generally don't have the best vantage point to discern just what exactly happened"
That is exactly when the refs should NOT blow the whistle. When they can't see the foul and aren't sure. What is this fear of not calling something just because a man is down. What happened to "I didn't see it", as the perfect, beautiful reason for a no-call.
The refs are not the floor to be super heros with special powers of divination. They have one job and one job only, to see or hear slaps of flesh on flesh while enforcing the general rules of the game (3 seconds, illegal defense, etc..). This used to be how the game was called and players, coaches and fans all knew it. Of course refs got yelled at and badgered for the calls they missed but at least the games had flow. Nowadays refs are calling fouls and stopping the game for things they think they see, things they think probably happened, things that usually happen in that circumstance, things that tend to happen, things that just might have happened, etc....They are not restricting themselves to calling THINGS THEY SEE AND HEAR. The refs actually think their job is to go above and beyond this. Someone should tell them they've gone astray, or been led astray. That reffing pro sports does not suddenly require super human divination. It's as simple and flawed as ever, limited by the number of eyes reffing the game, an inherent weakness that should again be accepted as the norm.
