Kansas City Chiefs
Andy Reid is undoubtedly the Chiefs’ best head coach of the past 50 years. That’s because he helped transform them from one of the NFL’s most frustrating franchises into serial Super Bowl contenders. Yes, Patrick Mahomes fell onto his lap but he also handled the former Texas Tech star perfectly. Mahomes brought the good times back.

If Reid has the freedom of Kansas City, the same can’t be said about Romeo Crennel. As far as the Chiefs Kingdom is concerned, he doesn’t exist. They went 2-14 in his final season before Reid came in and turned them around. Crennel’s tenure was a disaster (via Deseret News).
