Big Movers Up the Coach Rankings Board
NFL Week 13 - The EdjSports Coach Rankings are based on team performance to date and fourth-down decision making to determine which coaches are best at maximizing their teams’ win probability. More specifically, instead of subjectively ranking coaches based on the “eye test” or trying to compare things like scheme, roster-building, and motivation, EdjSports uses data to analyze and rank NFL coaches with a strong emphasis on 4th down decisions making. Games can be, and often are, won and lost on fourth downs alone. So coach rankings consist of two factors: performance to date, referred to as Edj Power Index, or EPI, and 4th down decision making, referred to as Critical Call Index, or CCI. For a deeper explanation please review EdjSports methodology below.
Brandon Staley (LAC), Matt LaFleur (GB), and Kliff Kingsbury (ARI) remain the top three with Frank Reich (IND) and Sean McDermott (BUF) swapping spots for fourth and fifth, respectively. Dan Campbell (DET) is the big mover of the week, jumping seven spots to 22nd overall, and up 14 spots to sixth in CCI, after the Lions got their first win and Campbell had the best fourth-down decision of Week 13. Vic Fangio (DEN) moves up two spots to 12th overall but has the second biggest rise in CCI, moving up five spots to 11th after a handful of aggressive decisions against Kansas City on Sunday night. Rich Bisaccia (LV) is down two spots to 26th overall after another poor week of fourth-down calls, dropping three spots to 28th in CCI. Joe Judge (NYG) also had another poor week on fourth-down calls, dropping him one spot to 31st overall, ahead of only Mike Tomlin (PIT).
EdjSports is widely acclaimed for its in-game risk management analysis and proprietary Game-Winning Chance (GWC) metric used by NFL teams and media. GWC is a team’s win probability at any point in the game and is generated from the proprietary EdjFootball simulation model. EdjSports is creating the industry standard for head coach rankings by allocating its GWC to coaching decisions.
Built on 20+ years of historical NFL play-by-play and statistical data, the EdjFootball model is a fully customizable simulation engine. It accounts for each team’s strengths and weaknesses on offense, defense, and special teams. Model inputs include game state (score, timeouts, quarter, clock, down and distance, and field position), venue characteristics (indoor, outdoor, grass, turf, elevation), second half kickoff team, key injuries and Football Outsiders DVOA. Each week the model evaluates team performances and adjusts team strengths and weakness accordingly. As a result of these analyses, over the course of a season the EdjFootball model simulates over 3 billion games to conclusion.
About the EdjSports Coach Rankings
EdjSports analyzes every coaching decision during the course of a season. The EdjFootball model enables an in-depth examination of all critical calls (fourth downs, PATs, and kickoffs), in terms of the amount of GWC at stake. The coach’s play-calling choices (run, pass, field goal, punt) are assessed at the point of decision (pre-snap) and rated with respect to their impact on winning the game. As a result of this process all play calling decisions can be objectively classified as either optimal decisions (correct calls) or suboptimal decisions (errors).
The EdjSports Coach Rankings are based on this methodology and consist of two main components that result in the overall ranking.
Edj Power Indexes (EPI) Ranking
This is a cumulative ranking of the Edj Power Indexes (EPIs) including Offensive Pass, Offensive Rush, Defensive Pass and Defensive Rush. This ranking is a reflection of how teams performed in every situation during the season.
Offensive Play Calling (CCI) Ranking
This ranking is based on an analysis of offensive play calling on 4th downs and compares teams in terms of GWC lost or gained, on a normalized basis so that all teams are given the same test. Additionally, the CCI rankings are adjusted to account for the frequency and situational nature of critical calls to allow for fair comparisons of all 32 teams.
EdjSports Coach Ranking
This ranking is a weighted average of the Edj Power Indexes (EPI) and Offensive Play Calling (CCI) Rankings that provides a more comprehensive assessment of coaching strengths and weaknesses.
