The way I word this might not make sense but I’m gonna give it a shot anyway. I think a good idea would be introducing contracts for fights. For example you could negotiate the split for the purse and decide if you wanted a rematch clause for the fight. And if you choose to have a rematch clause then what the split would be for the winner and loser of the first fight. I do see that that would lead into having AI managers which would be a lot of work.
Yeah I agree, giving more options on contracts/fight negotiations would be a good change.
More options, percentages and a few other things are much needed in contract terms. Also the fighters expectations will be made clear in terms of where they want to be career wise during contract.
