The XFL will Air Games on ESPN, ABC, and FOX

To me, college football appears to be an inferior product, but people seem to love it, quite obviously.

That's clearly something entirely different, since it's so long established, but having fans watch less than the best competitors in the game isn't impossible. But expecting it to be any sort of main stream success in comparison to the NFL is insane. Somehow the MLB, and to some degree the NHL and NBA all have had some level success with a minor league of sorts. But somehow the extraordinary popularity of pro football hasn't left any room for a lower level pro league in a long time. 

I think generally that's because everyone has gone about it the wrong way. From the XFL the first time around, to NFL Europe, to the AAF this past year, and seemingly the new XFL next year.
