The WNBA is an American team sport. Is there a WNBA GOAT? I have no idea as I don't follow it.
Funnily, they just recently did a fan vote of it. Diana Taurasi won it. 3 Championships, 2 Finals MVPs, 1 MVP, 14 All-WNBA appearances, 10 All-Star appearances, all-time scoring leader, 5 time scoring champ, 6 EuroLeague titles, 7 Russian league titles, 3 NCAA titles, 2 Naismith awards. Lots of accolades.
I personally think Lauren Jackson is the WNBA GOAT.
