Next Level Stats provides detailed NFL analytics and interactive statistical leaderboards built from play-by-play data. Its 2026 Passing Rating Leaders page ranks qualifying players and displays metrics such as passer rating, passing yards, completion percentage, touchdowns, interceptions, sacks, fantasy points, expected points added, completion percentage over expectation, success rate, and average depth of target. The page notes that its analysis draws on more than 1.2 million plays spanning 2000–2026, and identifies the current 2026 leaderboard as covering games through week four, with 53 qualifiers and no minimum participation threshold.

Users can explore data by category, position, statistic, season, date range, and game situation, including third downs, red-zone plays, deep passes, and home or road games. Filters also cover regular-season and playoff games, draft rounds, and college conferences. Leaderboards support sorting and player searches, while direct links provide player-level splits derived from play-by-play information. Beyond passing, the site features rushing, receiving, and defensive statistics, along with player leaders, team rankings, standings, draft information, and insights.
