Miami @ Kansas City on Peacock ...

19. Reasonable

But, while I realize this is a postseason game, they're got 34 weeks of data from Amazon Prime.
All your points make sense as to why they might be doing it, but I still think it's illogical for them to run this test with a broadcast partner that OWNS a primary means of delivery.
Amazon Prime didn't even have that, so if national ratings are way off because of that model they know the answer.
That said, because many of those Thursday games were stinkers, maybe they feel they need a fame likely to be worth watching. Still stupid.
Oh, and if that's right, they're testing in a game with two teams based on passing, one from Miami, in zero weather & windy conditions! Oh, the irony.
