USBAIn 2K there is no "I was home" checkbox on a logged score, and the league does not take anyone's word for who hosted. The venue comes from the Team Comparison screenshot: the away team is on the left, the home team is on the right, and you confirm that orientation on the review screen when you attach it.
How much the schedule already knows depends on your league's length:
- In 29- and 58-game leagues, the screenshot is the only venue source. A game with no box score has no confirmed home team and shows as a neutral matchup until someone attaches one. Want your home games to count as home games? Post the screenshot.
- In 82-game leagues, the schedule already plans who hosts — the full-season format lays out each team's home and away games in advance, so the matchup knows its expected venue before a game is even played. The box score still records the game that actually happened; post it so the stats and the result are on file.
- Postseason games always wait on the screenshot for their venue, in every league.
