I have never liked the call! the flopping warning then the subsequent tech(s).
Why call anything other than a foul (if there is one)(and I don't mean calling a flop as a tech either, let it go)? If a player flops and play is allowed to continue, it is the flopper's team that suffers, who now have to play 4 on 5 or a fast break scenario with a loose man on O.
Besides that, I honestly think, sitting in my chair and watching the action, that a lot of flops aren't that at all. I don't mean that they are all fouls but simply that players do lose balance at pace, sometimes the slightest touch can send you tumbling, heck, we even applaud when a cross-over "breaks ankles" and the defender falls, do we want those called as flops? Let it go. If a player wants to accentuate his flop by staying down and playing really, really hurt, blow the whistle, insist on an "injury" sub for the "flopper" (once again his team suffers) and get on with the game (if the downed player is really hurt, he should be glad to get off and fixed up and back after treatment). Self regulation may save this issue in the end.
And then the game can flow again as everyone says they want.
