While ESPN and TNT didn't extend their media rights deals with the NBA before their exclusive negotiating window closed, sources tell Front Office Sports that both networks have matching provisions that allow each an opportunity to respond to outside bids before contracts are finalized. The provision applies to both streaming and linear rights packages.

The NBA currently gets nearly $2.7 billion annually from its nine-year $24 billion deals with ESPN and TNT expiring at the end of next season and a doubling of that annual average is possible. 

The NBA has been tied to WBD in various ways since 1984, while ESPN has been a partner for more than 20 years. ESPN also provides significant programming beyond live sports that help promote the league.
