library(ffsimulator)
library(ggplot2)
library(ggridges)

mfl_conn <- mfl_connect(season = 2021, league_id = 22627)

## OTHER PLATFORM CONNECTIONS MAY BE USED, FOR EXAMPLE:
# sleeper_conn <- sleeper_connect(season = 2021,  league_id = "652582284720971776") 
# flea_conn <- fleaflicker_connect(season = 2021, league_id = 312861) 
# espn_conn <- espn_connect(season = 2021, league_id = 899513)

### Build Schedules

Source: https://ffsimulator.ffverse.com/articles/custom

Generates randomized head-to-head schedules for a specified number of seasons, teams, and weeks. It uses the circle method for round robin scheduling and shuffles assignments.

```r
schedules <- ffs_build_schedules(
    n_seasons = n_seasons,
    n_weeks = n_weeks,
    seed = NULL,
    franchises = ffs_franchises(conn)
  )
```
