It's a bit unorthodox, but my idea was that I would give each team in the league a 1-100 rating, and then generate the amount of numbers per games in the season. Any number less than or equal to the rating would count as a win, and anything greater than would count as a loss.

This is from my NAFA thread:

How I Simulate
Each of the six original teams was assigned a rank based on the story. This is the only thing that isn’t random. The best team received six points, second five, third four, etc. Then, each team was entered into a list a certain number of times based on the amount of points they had.

The next year, the points are based off of the standings from the previous year. So the champion gets the most, runner-up second most, etc. The process is the continued for each season.

When there is an expansion team, a rank is randomly generated from the bottom half of the league. The team then takes this rank and pushes all other teams down a rank.

For the championship, the two teams are entered into a list the same way as during the regular season. However, the team with home-field advantage gets added an extra time (Home field advantage will no longer be a factor in 1955, when a neutral site will begin hosting the Continental Championship).

I've always thought xkoranate was a great program for simulations. It pretty much has any sport that you can think of and once you figure out how it works, it is really easy to use. I was using it for some personal projects, but the laptop that had xkoranate bit the dust over the weekend so I don't have a way to use it. I've got a Chromebook, but of course xkoranate doesn't work on a Chromebook, like pretty much any other somewhat big program 

I have xkoranate and i have no idea how it works

The way I work things for my football league (COMING SOON!) is that each team gets a score between 0 and 100 for offense, defense and special teams. Those are then merged with weighting based on whether the coach is offensive minded, defensive minded or balanced, and always 10% on special teams. So for an offensive minded coach, it's Offense 55%, Defense 35%, Special Teams 10%. Defensive minded coach flips offense and defense scores, and balanced moves those to 45-45-10. Rating numbers have the decimal place then moved one spot to make the rating between 0.0 and 10.0 (important for the simulation).

Off-season, each team's rating for the three will be modified to account for players getting better, worse, player additions and player losses. Much of this is random, however, I'll move the numbers manually if I feel they added or lost something very important. In later seasons, there will also be a separate QB score that will be factored into things, as, much like the NFL, QBs are going to be the most important position.

From there, I simulate the results of each game using an online dice roller, home team gets a d12, away team gets a d10 with their rating added to the roll. Ties broken with a d4 added to each.

I'm very intrigued by this! Are you doing this in Excel to crunch the numbers or just manually? I definitely want to hear more about this.
