Many had tipped Clyde as promotion favourites last season based on their appointment of Barry Ferguson as manager, but the former Rangers midfielder has had to return to the drawing board after failing to even reach the play-offs.
The former Blackpool boss has been ruthless with a squad that even flirted with bottom spot and appears to be placing his faith this time on players with recent experience of the Scottish Championship.
Fellow former Scotland international Gary Naysmith has had a similar clear-out of an East Fife squad that also under-performed by finishing fourth in the table, although they did pick up in time to reach the play-off final, where they lost to Stenhousemuir.
Defender Julen Etxabeguren Leanizbarrutia and goalkeeper Alan Martin have made the biggest jump up the ranks during the close season.
Former Real Sociedad 24-year-old Leanizbarrutia has left East Fife to sign for Dundee, while Martin has left Clyde for Hamilton Academical.
Annan Athletic and East Stirlingshire have had their annual mass cull of their squads, with Berwick Rangers the most active in adding to their numbers.
