@EricStein and @Sammi Brie witnessed this in Phoenix when Scripps forced the CW off of KASW onto KNXV's Antenna sub (which, in retrospect, does show how little Scripps wanted to do with the CW at that point). Nexstar couldn't wait to get off of there.I don't see how it would be any different than paying for carriage of Antenna TV or Rewind, which they legally do in plenty of places where they don't own stations. Obviously, I'm not an attorney, but it seems comparable.
Why not Rewind the other 22 hours? It's Nexstar's, they already own it, and it doesn't have an affiliate in Detroit or Miami.
