Jordan Turnbull and Alan McCormack were among 13 released in July, Scott Wharton and Callum Morton have returned to their parent teams, while skipper Charlie Goode became the club's first £1million pound player when he signed for Brentford.
So, with all those going one way and another nine coming in, how is the squad shaping up for Saturday's opener against AFC Wimbledon? Let's take a look...
17. Midfield: Ricky Korboa
An unknown quantity having joined from non-league but he has plenty of exciting attributes and a terrific attitude to match. Another player that may provide an injection of attacking impetus from the bench.
18. Forward: Morgan Roberts
Featured regularly in pre-season and Curle's mounting injury problems could give him an opportunity to impress early in the season, but he'll have to take it given the competition for places.
19. Forward: Matty Warburton
Became a bit-part player last season but has forced his way into the reckoning with some sharp performances in pre-season. Still has the hunger and ability to be a success at the Cobblers.
20. Forward: Joe Nuttall
Didn't boast the most impressive of goal records at Blackpool - four in 33 games - but Curle is confident he can get the best out of him, just as he did with Oliver. Clearly has something about him - can KC unlock his potential?
