Dennis Allen not expecting to make any staff changes going into the Bye

In the multiple 7-9 and 9-7 seasons under Payton, how many times did Payton make coaching changes during the season?

The only one that I remember is replacing Ryan with Allen as DC, but the foundation for that change was put in place before the season started. It was a contingency plan, and an inevitable one, that Payton put in place before the season started.

Coaches don't usually make staff changes in the middle of a season, especially if their record is .500 or better.
