1. Andy Reid, Kansas City Chiefs
There was a long period of time there where it looked like Andy Reid was just a good regular-season coach. His teams often had great regular-season records and would fall short in the NFL Playoffs at one point or another. Then Reid helped draft Patrick Mahomes and that all changed.
Obviously having the best quarterback in the league helps Reid's case but it has also helped Mahomes' career that he was drafted to a team that is willing to be creative and utilize Mahomes' incredible talents.
Sure, he may have his issues with clock management at times and he is by no means perfect (no coach is), but it is impossible to deny that Reid is one of the four best head coaches in the league. You don't win two Super Bowls in a four-year span and not earn that distinction.
If anything, Reid's lack of success in the playoffs should remind fans just how hard it is to win a Super Bowl. Winning a Super Bowl shouldn't be the only measuring stick for a head coach, especially with such a small sample size. Sometimes it simply takes time and a team needs everything to break its way.
There really isn't much that can happen for Reid to be knocked off the No. 1 spot on this list. The only way he doesn't rank first at the end of the year is if Payton wins the Super Bowl with Denver and the Kansas City Chiefs somehow miss the playoffs. Both of those things obviously aren't happening.
