One common NBA 2K22 MT is that players put their team's starters on the same page and then slack on the rest of their team. In reality, it's best to have three or four good players rather than one star player. The reason this is true is all about stamina.
The players who are great in the bench can benefit from stamina constantly, running constantly taking rebounds, pushing players down in the post or on the field, etc. This is true, but the bench player can come in quicker and both players can sprint around with maximum energy each and every minute.
Don't put any money into a card unless you expect it to be a regular part of the lineup for a while. When players have ten cards they can count on to be part of the lineup, grade all ten at the same time. This will result in a faster procedure and results in that the entire lineup produces an MT throughout the game.
The drawback here is that the cards can't be used for a while when grading. You can still use ten cards simultaneously prior to leaving to work and then return to a machine for making currency. If the cards are still being evaluated, play some single-player contests while the process finishes, it's worth the effort.
The leavers won't lose their $10,000 MT 2K22 and those who are still in the game can take on some easy AI opponents. It's quite a task, but, with 10,000 VC likely to be the only line to every thrown match it's possible to make money, with low risk.
