Once you have played you your league the person with the most knockout and submission wins should get a trophy of somekind.

Also obviously the league are new but I think a format would work better where you can only fight each player say twice in your league and there for the most amount of fights you could have in the league would be 198 and you must do this within the alotted time. This would stop people who just more active and can have hundreds upon hundreds of fights because they have no job/lives... and it would determine a true champion as once a lot of people get to the max fights it will come down to who won most etc.
