hmm i c. well merchandise fluctuates a lot, so I'm not sure if that 10k loss came only from selling your 2 players.
If that rule applies, that could mean that I should be able to earn about extra 10k by having 4-5 balls on that category as oppose to 1-2 balls. At the beginning of the next season I'm gonna sell some of my players and replace with the cheaper one to save a lot of money. After that I don't intend to sell anybody for 1 season, so I could see if the merchandise increases. Ofc there are so many factors to consider, so I'm not sure how it will come out, but at least I'll observe if it makes any difference to my merchandise.
