Kansas City Chiefs: Ranking head coaches from Andy Reid's tree

4. Ron Rivera

Ron Rivera joined the Eagles as the linebackers coach in 1999, working under Reid. Rivera's tenure with the Eagles saw the team reach the NFC championship game for three consecutive seasons. He played a significant role in the development of linebacker Jeremiah Trotter, who achieved All-Pro status twice under Rivera's coaching.

Rivera would leave Philadelphia after the 2003 season but did not get a head coaching chance until the 2011 season. He became just the third Latino head coach in NFL history when the Carolina Panthers hired him. It took three seasons for Rivera to record a winning record, but his aggressive nature won him over with fans as "Riverboat Ron".

From 2013-2018, the Panthers alternated losing records with winning ones, including an amazing 15-1 record in 2015. With McDermott alongside him, the Panthers won two playoff games to reach the Super Bowl that year. Rivera had only one other postseason win in three appearances, frustrating Panthers fans. A 5-7 start to 2019 was the final straw and Carolina decided to fire Rivera. He ended with a 76-63-1 record in Carolina, good for the most wins in franchise history.

Rivera landed on his feet with the Washington Commanders in 2020, serving as a guiding light to a franchise in turmoil. He has 22 wins in Washington, the most in franchise history through a coach's first 50 games. The 61-year-old Rivera may be winding his career down, but he can certainly attribute his steady climb in the league partially to Reid.
