Andy Reid
Reid is the only coach on this list but he deserves a mention. He underwent one of the greatest career revivals ever when he joined the Kansas City Chiefs. This came after Philadelphia opted against renewing his contract. He did a brilliant job for the franchise but they fell short of Super Bowl glory.

Some people thought that Reid was burnt out and wasn’t a winner. But he proved his doubters wrong when he guided the Chiefs into contention. Then he transformed Patrick Mahomes into the NFL’s best player and became a two-time champion. It’s an inspiring story and it helps that he’s so likable (via The Athletic).
