Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
The question begged is when will FIFA finally get around to it?

Nope. Not even Michel Platini of UEFA will implement goal-line technology.
Alas, you're right. But we can hope can't we? After all, the flop in the NBA evolved slowly over time. In the 1980s it was non-existent. In the 1990s it was known as Divac's signature move, but it was more so ridiculed than assimilated. I blame the 2000s era of Allen Iverson-Kobe Bryant hero-ball. I stopped watching basketball during the peak of hero ball (2001-2005) when isolation plays, ball-hog shooters, and egocentric personalities dominated the NBA. Yes, a good portion of this blame should fall on Michael Jordan, who created the myth that one player could change a team. It was a myth. Did MJ win it big for the Bulls when he scored a still-standing NBA record 63 points in a play-off game? No, Chicago was still eliminated from that series. Jordan didn't get to make his true impact until the Scottie Pippen-Horrace Grant-Phil Jackson era, and thrived even BETTER when Rodman replaced Grant by bringing that smothering Defense to basketball which gave MJ's hero-ball antics even more opportunities to take shots. Kobe grew up on this, and tried to make it his game. This is why he and Shaq conflicted so much, because a driving center like Shaq depends not on hero-ball, but good movement and distribution to get good looks or to use screens to open up shots for other guys. This is what Lebron is doing so well today, folks know that he can shoot, so you have to put coverage on him even if he doesn't have the ball. (Think about how good Stockton and Malone were at this) This is the core of Heat's pace and space, spacing the floor through screens and fakes to open up shots for perimeter players.
I think that when Steve Nash got the MVP in 2005 that signaled the end of hero-ball era in NBA. Kobe was crying to get traded!! The Hero-Ballers were in serious decline, and distributors were on the rise. We are in the peak era of distribution b-ball. Now if a team doesn't have an 8 assist plus distributing PG they simply can't even make the play-offs it seems! Even the Lakers two-time Championship run was built on Pau Gasol getting 6-8 assists a game. If teams don't have the guard to make the passes, they going Point-Forward like Scottie Pippen and Magic Johnson did to distribute the ball. Again, this is what Lebron does best, but he is not alone. This is the new NBA. An NBA that I LOVE to watch! It is become strategic, mathematical, like a very good soccer game. Phil Jackson's Triangle was similar, but it required very well-crafted pieces. The "positionless" pace and space of the Heat is looking like the new Triangle, a dominating strategy that takes into account all the current playing types in the NBA.
Hero-Ball I feel brought the FLOP to the forefront. Hero-Ballers could get to the line 20 times in a game and win it almost solely by free-throws (yeah Kobe, I'm looking at you!!!). You could look at the box-score game after game, team after team, and see the differential that won the game was generally who had the free-throw advantage. The entirety of the NBA began to play hero-ball, and master the FIFA flop (yeah Derrick Fisher, I'm looking at you too!!). Today, even guys like Lebron flop, though laughably sometimes Lebron does it so obviously on purpose that I swear he is MOCKING the flop rather than trying to use it!!
I hope that getting rid of the flop brings back that high scoring offense of the 1970s, or the beautiful distribution of the Showtime era. Hopefully we are in the process of an NBA renaissance, and I for one am so glad to be back. I was big into basketball from 1992-2001, then walked away completely until 2009 when it looked like Hero-Ball was ending. Oh, with guys like KD shooting buckets all day, its still creeping in there, but even while KD's shooting style is remniscent of hero-ball, his actual personality and vibe is far from being the kind of "I got this one guys" of the likes of Kobe or Iverson (or even Jordan for that matter). Its a great time to be basketball fan again
