As many as 40 players wore the Spireites shirt as James Rowe ripped up the squad in November following his appointment as manager.
And the changes paid off as Town went from relegation strugglers to promotion challengers.
Some of those who feature below did not make enough appearances to be accurately judged, while others were regulars and made a big impact.
Here is how Liam Norcliffe rated each player out of 10 this season...
1. Kyle Letheren 7
Started the season as the number one goalkeeper under former manager John Pemberton. He made 16 starts and recorded seven clean sheets, including five in a row when James Rowe was appointed boss. He left to join Morecambe in January and won promotion to League One through the play-offs.

2. Corey Addai N/A

3. Dylan Wharton N/A
The young stopper made his first professional start for the club in the FA Trophy against Boston United in January and he was the hero in the penalty shootout. It was his only appearance of the season.
