BC is already up against College Football. Do you really want to take on the NFL Sunday? Or run races Friday when no one is watching?

Whomever said TV guys were against this hit it on the head. No one wants to counter program the NFL with an unpopular sport. They'll run non-sport programming since that will attract a bigger audience than the miniscule portion of the sports audience that prefers horse racing to NFL football.

This is a niche sport website. Just because the majority of posters here might think this is a good idea doesn't mean any network that tried it won't go broke.
