Where's this ranker data coming from?
This is also why the TV ratings rev share model is seriously flawed. There's soooooo much nuance about ratings performance. Network, daypart, opponent, competition, weather, etc., etc., etc.
A team might be delivering huge audiences on, say, CBS Sports Network, if you control for other games on that network, subscriber count, and competition. But in absolute terms their ratings might rank poorly. Give them an ABC noon game and it'd be much different, potentially.
The whole model is kinda dumb, but the dopes in Tallahassee demanded it. Clowns.
