And if Amazon really wants to overpay, I see no reason for putting any games on cable. To hell with ESPN, and FS1 viewership is awful. If we can get teams to schedule more conference games and bye weeks in September, and let's say that we hypothetically have 16 teams each playing 9 conference games and let's say 2 home non-cons, that would be 104 games over 13 weeks, or 8 games per week. I'd say the most optimal outcome would be selling 4 to over-the-air and 4 to Amazon. Provided that we can actually Fox/CBS/NBC to buy 4 games and that Amazon really does want to overpay. That would be a pretty sweet outcome IMO.
The risk in this is putting your games outside the reach of the average fan. The current paradigm has its problems, but until it shifts, having games exclusively on streaming is going to hurt both in terms of viewership and buzz among those who have not made the jump. ESPN has no reason to talk about you, no matter how good you are, at that point.
