Sure, but it's much easier to see ROI on 11 million viewers per game vs 1.4 million viewers per game. The NBA is asking for double what the NFL asked for with a package that is going to have less total viewers. I think in the end $1 billion for 15 NFL regular season games makes sense pricing wise considering they don't get playoffs nor are they included in the Super Bowl cycle nor do they get to flex games (The NFL can, but Amazon can't like the other networks). I don't think it makes sense to pay $2B+ for a few exclusive games per week over a 19 week season while also needing to pay for all of the infrastructure of broadcasting.
The NBA needs Amazon more than Amazon needs the NBA in this case because they allow a bit more leverage against TNT. I don't think Zaslav's math on this is wrong. TNT won't have buyer's remorse if they decide to match and the NBA picks them, but if Amazon's is chosen and there is buyer's remorse like Apple with MLS it's going to kill future TV deals.
I've always thought the streamers are all trying to figure out a way to buy themselves into the Super Bowl cycle because that's the crown jewel of US sports, everyone knows it, and the NFL is going to charge a premium to be added to that list. ESPN paid extra for ABC to get added to the cycle. If Amazon doesn't get the NBA package I don't think they'll be heartbroken because they have TNF which is 165 million viewers per season and a pathway to bid on NFL playoffs.
