I see no athletes in any other sport willing to do that, do you? In some ways it’s far more of a TEAM sport. It’s been incredibly exciting hockey IMO. There was some vid of Lebron doing some backwards dive over exaggerated drama, looked so ludicrous hen you think of what hockey players endure.
Flopping in basketball is ridiculous and at one point the NBA was actually cracking down on flopping with some penalties. They need to actually make it a technical foul and then if they start calling it perhaps something will improve. That said, there is some degree of "diving" in hockey, and occasionally the worst offenders in this category draw a two minute penalty for it.
