+# Phase 1 Plan 03: NFL + Orchestrator Refactor Summary
+
+**Created NFL sport module and refactored scrape_schedules.py to thin orchestrator, completing Phase 1: Script Architecture**
+
+## Performance
+
+- **Duration:** 8 min
+- **Started:** 2026-01-10T06:10:46Z
+- **Completed:** 2026-01-10T06:18:23Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Created `Scripts/nfl.py` with NFL_TEAMS (32 teams), 3 game scrapers, 3 stadium scrapers
+- Refactored `Scripts/scrape_schedules.py` from 3359 to 733 lines (78% reduction)
+- All 4 core sports (MLB, NBA, NHL, NFL) now have dedicated modules
+- Phase 1: Script Architecture complete
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create nfl.py sport module** - `a6c9230` (feat)
+2. **Task 2: Refactor scrape_schedules.py to orchestrator** - `b93205e` (feat)
+
+## Files Created/Modified
+
+- `Scripts/nfl.py` - NFL team mappings, ESPN/Pro-Football-Reference/CBS scrapers, stadium scrapers
+- `Scripts/scrape_schedules.py` - Thin orchestrator importing from sport modules
+
+## Decisions Made
+
+- NFL uses cross-calendar-year season format (2025-26) consistent with NBA/NHL
+- Non-core sports kept inline with TODO comments for future extraction phase
+- Orchestrator maintains backward-compatible CLI interface
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## Phase 1 Complete
+
+Phase 1: Script Architecture is now complete with all 3 plans executed:
+- 01-01: core.py + mlb.py (shared utilities and first sport module)
+- 01-02: nba.py + nhl.py (second and third sport modules)
+- 01-03: nfl.py + orchestrator refactor (fourth sport module and thin orchestrator)
+
+### Module Architecture
+
+```
+Scripts/
+  core.py           - Shared utilities (385 lines)
+  mlb.py            - MLB scrapers (412 lines)
+  nba.py            - NBA scrapers (412 lines)
+  nhl.py            - NHL scrapers (412 lines)
+  nfl.py            - NFL scrapers (573 lines)
+  scrape_schedules.py - Orchestrator (733 lines)
+```
+
+**Total modular code:** 2,927 lines across 6 files
+**Original monolithic:** 3,359 lines in 1 file
+**Net change:** More organized, testable, maintainable code with clear separation of concerns
+
+## Next Phase Readiness
+
+- Phase 1 complete, ready for Phase 2: Stadium Foundation
+- All 4 core sports modularized with consistent patterns
+- Orchestrator provides clean entry point for all scraping operations
