When in Rome do as the Romans did... In this case the idea would be to create a public-private partnership that promoted the sport of Mixed Martial Arts Rugby and split the profits evenly, the private side using its profits for whatever it wanted to and the public side using its profits to pay down the debt.
The sport itself would combine the basic rules of rugby with the more primitive rules of mixed martial arts tournaments. Basically teams would be able to kick the crap out of each other on their way towards scoring a goal. It wouldn't be a game totally lacking any element of strategy though. For instance, each team would have to decide whether to keep all of their players concentrating on moving the ball or give some of them the task of trying to put opposing players into submission holds (which would remove those who submitted from the field and give the team who won the submission a numbers advantage).
