When you put it that way, it sounds unsustainable!
Seriously though, it's a little bit of an exaggeration - maybe average $90K? Anyway, my team is not really very good, but I have some money, don't really need to build out my arena anymore, get good merchandise revenue, don't have viable trainees anymore - so I think it would be fun to field a team that can utilize most offenses so that I won't be predictable.
I'll probably sell off someone later in the season also.
