Arena football ( http://en.wikipedia.org/wiki/Arena_football#Rules_of_the_game http://en.wikipedia.org/wiki/Arena_football#Rules_of_the_gam... )fits that bill, though it would be nice if we could also have NFL-caliber players, full-size field, etc. Sadly, the long and frequent delays allow for the spectacle at the stadium itself (cheerleaders, dancers, contests) and advertisements elsewhere, so I wouldn't count on the NFL itself doing away with them.
