Unrivaled basketball league debuts with Breanna Stewart and Brittney Griner during WNBA offseason

Unrivaled, the U.S. basketball league co-founded by WNBA stars Breanna Stewart and Napheesa Collier, is ready for its closeup.

The new 3-on-3 women's basketball league will debut Friday night, a couple of years after the idea of starting a domestic league to bolster athletes' salaries during the WNBA's offseason without them having to go overseas.

"Because a lot of players probably my age and a little bit older are so accustomed to going overseas," Stewart told CBS News. "And now it's like, no, you play WNBA. You come to Unrivaled and we're gonna take care of you. We're gonna pay you. We're gonna make sure you continue to build your brand.
