The WNBA is able to take innovative risks and try new things where the NBA can't. Some innovations have been strictly iconic: The constant pumping of Melissa Etheridge songs into the building, the orange and white basketball, team names with no 's' at the end, the creative armpit hair styles, etc.. Some of them are game innovations, like the two handed chest high push shot -- aka "the heave."
When Paul Westhead, one of the game's legendary creative geniuses, took over as head coach of the Phoenix Mercury, he developed a system where he'd rotate only two subs in the game, playing the same seven players every game. Each Player focused their game strictly on only one statistical category. For example, the center would focus only on getting as many rebounds as possible and the point guard assists. By having this singularity of focus on a particular stat, they'd often come out ahead and win the game. This groundbreaking group of seven players - often referred to as the Mono Stat Seven - changed the game forever. And while Westhead eventually died of ass cancer, his innovations still live on in the game today.
