Look at a cable bill and the sport is rarely one line. There is the tier itself, then in most American markets a regional sports fee attached whether or not anyone in the house watches it, and then pay-per-view billed separately on top of both. All three of those disappear here, and the competitions do not.
What is harder to guarantee is behaviour under load, because sport concentrates demand into a single minute in a way nothing else on television does. The matrix below sets out which leagues are carried and on which broadcasters. Judging a provider on that list alone is a mistake, though: what actually decides the evening is what the servers do at eight o'clock on a Saturday, and no table can show you that. The trial can.
