Allowing a certain number of players to play in a week to get rid of player advantage
The NBA schedule is variable with some teams playing way more games. If each team gets 25 or so starting players a week than the matchup is fair. Otherwise one team can have 40 players going while another has 30. Reason football is fair is because everyone has same number of players that week.
I would not expect this to be changed.
The main reason is because there are days during the week when there are near full schedules, meaning all 13 of your players have games but you can only start 10. Your opponent, on the other hand, has only 9 players with games.
This does not give you a 4 game advantage for this specific date. It give you a 1 player advantage.
Another reason is players being sat in either the 1st or 2nd game of back-to-back sets, especially the older players and players dealing with nagging injuries. Just using the team's schedule to count possible games does not factor in situations like this where it is known the player won't play in every game.
