It might be possible to get the "big dogs" ie NCAA, NFL on board somewhere wayyy down the line. But Im assuming they would fight this tooth and nail?
Any legal advice?
you will have to consult a lawyer to know how to obtain the rights to transmit these games, I think this is your main and biggest obstacle. I do not know if I misheard and i do not remember where I heard, but I heard that to acquire rights to broadcast these games the media pay a lot of money. I do not know if this is true.
No idea is bad if you can execute it.
The biggest obstacles are where to get funds and the bureaucratic issues that often take a lot of time
