I created a Monte Carlo simulation for a sports league.

The singular simulation works perfectly fine on its own. The sim that the Monte Carlo sim is going to be based on.

In the singular sim

Team 1 wins 12
Team 2 wins 14
Team 3 wins 10
Team 4 wins 8
Team 5 wins 10
Team 6 wins 6

When I run the thousands of sims is where the issue comes up. Each individual one is fine. The issue I am having is, how do I get each sim to involve each team?

For example
In sim #1
Team 1 wins 13
Team 2 wins 7
Team 3 wins 13
Team 4 wins 8
Team 5 wins 11
Team 6 wins 10

Each individual win total is fine but when added up would not create a possible season. Numbers should always equal 60. So how do I get each line of the sim to account for what the other teams did?

I hope I explained that well enough. Please feel free to ask if it didnt make sense.
