1) Well, I've seen my son give all out efforts already and win already, and he has never done that. He's pretty philosophy-driven (which he got from me, but his philosophies aren't always the same as mine), so unless he changes his philosophy about flopping, then I don't see him doing this...again, unless he is really having a major issue.
2) We'll have to disagree about it showing off...it most assuredly is that.
3) I think calling out floppers who do so for attention is hardly "stealing the spirit of the human soul". That's a bit much, brother.
