I've said it before and I'll say it again, the NFL Europe of late rule worked great; each team gets an equal amount of drives (as in posession but they have to field the offense). i.e. team A starts, fails to score, team B scores and wins. Team A makes a FG, team B makes a TD, B wins. A makes FG, B makes FG, still tied continue on. Lots of spectacle for the fans and honest as well.
