How does MY TEAM work?

[juon]

I have no idea how 2k is counting the effort every player makes a night.
Is there a known formula?
Is it similar to fantasy games?
I wanna know how the value of a player increases.
Some players i can sell some not???? (they all played last night)
Players with no fouls and no turnovers decreases ???
Please 2k show me the rules of My Team.
