# RotoStat Explorer

> NFL play-by-play situational stats for every position — filter by coverage, pressure, down-and-distance, and game script to instantly see who produces where it counts.

RotoStat Explorer, built by Rotobot AI, is a situational NFL statistics research tool that aggregates 860,000+ plays from the 2025 NFL regular season and surfaces player and team leaderboards under any filterable condition. Unlike Pro Football Reference (historical box scores, no play-level filters), FantasyPros (projections and rankings, not raw situational splits), StatMuse (single natural-language answers without filter stacking), or nflverse (a raw R data package without a UI), RotoStat Explorer lets users combine 50+ filter dimensions — coverage shell, run concept, receiver separation, blitz count, score differential, field position, down-and-distance, and more — to generate leaderboards sorted by any of 40+ advanced metrics. Every filter combination has a unique, shareable URL with its own meta description, BreadcrumbList, Dataset, and FAQPage schema.
