How do i reset the team rankings to default?

i want to set the team rankings back to how they were so New Jersey is 5th, Washington 15th, etc.
because i noticed that the rankings change as you play the game
so how do u set them back?

If you mean during a Franchise, you can't. As players are injured, traded or starting lineups changed, the team rankings are re-calculated.

If you mean in the default rosters, just reset your rosters.
