Because the #1 driver for Netflix, etc is ratings. There is only so much bandwidth and interested eyeballs for sports product around the globe (and they do think globally). You have to have some sort of compelling storyline for these shows to work. Last Chance U worked for a couple of seasons - but after that, it was a lot of the same stuff over and over. #1 recruit in the country going HBCU is a compelling story. #1 recruit going to Bama to play with the last 4 years #1 recruits for the 2,345 time National Champ, is not a compelling story.
