Brady went in with the same small ball offense against Miami and Miami stuffed it. It took Brady too long to adjust and they probably practiced nothing in an open offense. Especially one that still featured Coleman who was jogging through lazy routes.
Atlanta game you are right, they weren’t prepared. Atlanta figured out how to use our motion against us and it’s why the protection calls were wrong. Cus they showed one thing and let the motion play out. Josh called protections and the D swapped the other way. Josh got confused. As did Brady on how to adjust to it.
