I don't think it's money on the table. Sports leagues know where there bread is buttered and they extract a ton of cash out of their fans. The Netflix model is just an order of magnitude less profitable and would cannibalize their existing channels.
The money on the table reference was in regard to the kind of interactivity one could add to a sports stream: camera angles, betting, fantasy\gaming stuff, stats, alternate commentary, etc.
It really should be it's own thing. It's more than just a movie\tv show in it's possibilities, and so doesn't just plug into a Netflix model.
