TNT Sports parent company Warner Bros. Discovery is attempting to make good on its bid to retain NBA rights, and has made its first big move in exercising its matching rights.

The company on Monday, as expected, submitted a formal response to the NBA’s 11-year, $76 billion rights deals with Disney, NBC Sports, and Amazon, meeting a five-day deadline to respond to the league. WBD is targeting Amazon’s “C” package. That set of rights, estimated at $1.8 billion per year, includes a conference final every other season, early-round playoffs in line with what is currently on NBA TV, weekly regular-season broadcasts, the Emirates NBA Cup, and WNBA rights, among other assets.
