Andy Reid

279 regular-season wins — the most of any head coach in the database era (1999–present).

Reid has coached 50 more regular-season games than Belichick in the 1999–2025 window and won 13 more of them. Add the playoffs and his career total is 307 wins (279 reg + 28 playoff) — within striking distance of Belichick's 296. He is the only coach in this database to log 27 consecutive seasons as a starting head coach.

The Kansas City era is a different coach: 70% win rate vs. 58% in Philadelphia.

In Philadelphia he was a very good coach who occasionally cratered (4–12 in 2012, 5–11 in 1999). In Kansas City he turned into a dynasty operator: 12 straight winning seasons from 2013–2024, with five 12-plus-win finishes and a high-water 15–2 mark in 2024. The 2025 collapse to 6–11 is the first sub-.500 season of his entire KC tenure.

Five Super Bowl appearances in six seasons — a denser stretch than any Belichick run.

From 2019 to 2024, Reid took Kansas City to the Super Bowl in five of six seasons — only 2021 was missed (a Bengals upset in the AFC Championship). For comparison, Belichick's tightest comparable stretch was four Super Bowls in five years (2014–2018). No other coach in the database has 5 SB appearances in any 6-year window.

Three wins (2019, 2022, 2023) put Reid level with Bill Walsh and Joe Gibbs at the top of the modern Lombardi count.

Ten consecutive playoff appearances in Kansas City — 28–17 across 20 trips.

From 2015 through 2024, Reid's Chiefs reached the postseason every single year — a 10-season streak that ended only with the 6–11 collapse in 2025. Career playoff record across both teams: 28–17 in 45 games, including 20 separate playoff appearances out of 27 seasons.

The seven Reid teams that *missed* the playoffs averaged just 6.4 wins — when his teams are healthy enough to win games, they almost always win enough.

Mahomes' 2018 (50 TDs) is the highest passing-TD total of any QB Reid has coached — by 19.

Reid has produced a Pro Bowl jump from three different quarterbacks. Donovan McNabb went from 8 TDs as a rookie in 1999 to 31 in 2004 (the SB year). Alex Smith — left for dead in San Francisco — posted his career-best 28 TDs in 2017, his last year before being traded for Mahomes. Then Mahomes stepped in and immediately threw 50.

Mahomes' 2018 isn't just Reid's high — it's still tied for the second-most passing TDs in NFL single-season history. Of the 7 QB seasons of 27+ TDs under Reid, Mahomes owns 6.

Reid was throwing 5–7 points more than the league a decade before everyone else copied him.

In 2005 — in a league that ran the ball 44% of the time — Reid's Eagles passed on 65% of plays. That's roughly the modern Mahomes-era pass rate, almost two decades early. He was a pass-first coach when 'establish the run' was still the dominant orthodoxy.

The pattern is consistent: in 24 of his 27 seasons, Reid's offense passed more often than the league average. The conventional 'West Coast play-action coach' label undersells how aggressive his volume passing always was.
