Max Team Exposure

[austinjohnson]

Is there a way to remove pitchers from the player pool that is counted as max team exposure. Here is my reason, you can easily control pitcher max exposure by just setting their exposure by name or in a spreadsheet, however batters takes more work because there are more of them. The reason is because tonight I set Miami max exposure to 10% and the pitcher took up most of this exposure. I would rather batters take up the exposure than the Pitcher.

I'm interested in this as well. Maybe we can add a set team max exposure function?

Max exposure for teams counted for team stacks, so if you want to exclude pitchers from team exposure you should exclude pitchers from stacks. Single users isn't used for team exposures.

@BenikaH Team exposure was added in previous release https://pydfs-lineup-optimizer.readthedocs.io/en/latest/rules.html#teams-exposures

Didn't see that. Thanks Dima!

@DimaKudosh I don't know if I made a mistake or if the team exposure doesn't work how I think it does, but using this code and the player list the max exposures don't match up

[DimaKudosh]

Team exposure works only with stacking, in your code sample you set stack with 4 players, so exposure for team will be number of lineups where 4 players with positions ['1B', '2B', '3B', 'C', 'SS', 'OF','UTIL'] from team / total lineups. Pitchers are not counted in your case
