Teams are going with the small ball approach. Instead of having role players, they have basketball players. This allows the game to flow a lot more freely. It opens up shots, allows fast breaks, limits fouls. Its not "playing no d" or "shitty d".. its just placing more emphasis on offense rather than defense. and it makes the game a lot more exciting in my opinion.
Im not saying Dantoni invented this style of play, but he brought it to the table and made it look good. thats for sure.
