The KBO implemented a league-wide salary cap for each team. From what I can tell, it's pretty strict also. I don't think I can do the actual salary cap because I don't think any teams would be able to sign players based on the salary demands of this particular league. I don't really want to go in an adjust all of the different salary demands (star player, avg player, etc..) to reflect the new salary cap. That is just way above my pay grade. I am thinking that maybe I could take the avg payroll of all teams and use that as a cap though. There also appear to be rules about how many foreigners can be on the roster and how much they can be paid. The new roster rules are NOT reflected in the KBO Quickstart. Neither is the salary cap. The roster rules really only affect the minor leagues. This could be mirrored in OOTP except the only option for minor league rosters regarding foreigners is either no limit, or none allowed.
