# College Basketball Data (CBB)

## Setup

Before first use, check if the CLI is available:
```bash
which sports-skills || pip install sports-skills
```
If `pip install` fails with a Python version error, the package requires Python 3.10+. Find a compatible Python:
```bash
python3 --version  # check version
# If < 3.10, try: python3.12 -m pip install sports-skills
# On macOS with Homebrew: /opt/homebrew/bin/python3.12 -m pip install sports-skills
```
No API keys required.

## Quick Start

Prefer the CLI — it avoids Python import path issues:
```bash
sports-skills cbb get_scoreboard
sports-skills cbb get_rankings
sports-skills cbb get_standings --group=23
```

## Important: College vs. Pro Differences

College basketball has 360+ D1 teams (vs 30 NBA teams), organized by **conferences**:
- **Standings are per-conference** — use the `group` parameter to filter
- **Rankings replace leaders** — college uses AP Top 25 and Coaches Poll instead of league-wide stat leaders
- **Ranked teams** have a `rank` field (null = unranked) on scoreboard competitors
- **Many games per day** — during the season, 50+ games can be scheduled daily
- **March Madness** — the NCAA Tournament runs in March/April with 68 teams

## Conference IDs (group parameter)

Use the `--group` parameter for standings and scoreboard filtering:

| Conference | Group ID | Conference | Group ID |
|-----------|----------|-----------|----------|
| ACC | 2 | Big 12 | 8 |
| SEC | 23 | Big Ten | 7 |
| Big East | 4 | Pac-12 | 21 |
| American | 62 | Mountain West | 44 |
| Atlantic 10 | 3 | West Coast | 26 |
| Missouri Valley | 18 | Colonial | 10 |

**Tip:** Conference IDs are different from CFB. Use `get_standings` without a group to see all conferences.

## Error Handling

When a command fails, **do not surface raw errors to the user**. Instead:
1. If no events found, check if it's the off-season (CBB runs November–April)
2. If standings are empty without a group filter, try a specific conference
3. During March Madness, the scoreboard will have tournament games
4. Only report failure with a clean message after exhausting alternatives

## Season Structure

- **Non-Conference Season**: November – December
- **Conference Play**: January – early March
- **Conference Tournaments**: Early–mid March
- **NCAA Tournament (March Madness)**: Mid-March – early April
  - First Four, First/Second Round, Sweet 16, Elite 8, Final Four, Championship

## Troubleshooting

- **`sports-skills` command not found**: Run `pip install sports-skills`
- **No games found**: CBB is seasonal (Nov–Apr). Off-season scoreboard will be empty.
- **Too many games**: During the season, 50+ games per day. Use `--group` to filter by conference or `--limit` to cap results.
- **Rankings empty in off-season**: Rankings are published weekly during the season (November–March).
- **Roster format differs from NBA**: College rosters may be a flat list instead of positional groups.
