13. John Madden, Oakland Raiders

What a run John Madden had with the Raiders. He led the team for just 10 seasons, averaging over 10 wins per campaign, and his .759 winning percentage is the second-best in the history of the NFL. Under his guidance, the Raiders won seven division titles. He was carried off the field by his players after their team won Super Bowl XI.

14. Bud Grant, Minnesota Vikings

The Minnesota Vikings got to four Super Bowls and won the championship in 1969. His Purple People Eaters defense also remains one of the best in the NFL history.

15. Andy Reid, Kansas City Chiefs

When Andy Reid is finally done with football, he will almost certainly be ranked higher thanks to his budding relationship with superstar Patrick Mahomes. He was very successful as the coach of the Philadelphia Eagles and has improved his stock since joining the Chiefs in 2013. He finally got his Super Bowl ring at the end of last year’s campaign and could be in line for much more.
