The WNBA and its players' union held 15 hours of advanced negotiations starting Thursday at 11 a.m. ET, making progress on core and peripheral issues without public updates from WNBPA Exec Dir Terri Jackson or Commissioner Cathy Engelbert. Talks, totaling nearly 40 hours this week, continued into pre-dawn Friday with increased urgency after the league's March 10 deadline passed, threatening the regular season start. Sources indicate Friday's session mirrors the momentum, as the league builds toward a pivotal moment. Players stand to secure a brighter future if a deal seals soon.
