When the Miami Dolphins fired Chad O'Shea as their offensive coordinator at the end of last season after just one year with the team, some were wondering why. Months after the firing occurred, it's been revealed that O'Shea was fired due to a bizarre reason.

In a piece for the Miami Herald, Barry Jackson, Adam H. Beasley, and Armando Salguero highlighted what led to O'Shea's firing. Some people close to the situation — including players — shared what happened behind closed doors in 2019.

“The Patriots offense is considered complex, but a player said O’Shea made the situation worse by trying to install especially complicated, advanced elements of the Patriots offense that (Tom) Brady and offensive coordinator Josh McDaniels used. Those plays and terminology might be second nature to Brady in years 17, 18 and 19 of his career there but would confuse young Dolphins who were learning the Dolphins offense for the first time.”

Last season, the Dolphins deployed journeyman quarterback Ryan Fitzpatrick as their starter under center. In addition, Miami also gave Josh Rosen a chance to make a few starts during the season.

While Miami didn't have a franchise quarterback, O'Shea attempted to implement an offense that Tom Brady was capable of running. However, on the other hand, the quarterbacks that the Dolphins had would need more time to learn the offense.

Instead of keeping O'Shea, Miami elected to bring Chan Gailey out of retirement to call their offense in 2020. It's safe to say that O'Shea didn't last long with the Dolphins due to the complexity of his offense. That shouldn't be an issue with the 68-year-old Gailey.
