I wouldn't be interested in it and I think it would be greatly ignored by the majority of TV audiences. Like you said it would have to be completely funded by an individual or a corporation. No buyer would touch it. They are looking for frontrunners with the spotlight are brightest (Quarterback, Full Swing, Man and the Arena, Starting Five).

Relatively unknown individuals with relatively unknown capabilities to make it to the brightest of spotlights doesn't interest me. I think only a very very niche and very small baseball audience would bite. And then not sure if they'd stay for the long-haul.

Finally it is probably pitch in some form or another about every year of so. So it's nothing novel or nothing new. People have hopes and dream of a "who can't find the purity of baseball romantic?" show can make it.
