Looking down the list of free agents - and applying some geographical sense in most cases - the following half dozen jump out at me currently:
Ben Garratt (29), Burton - previously suggested on here, vastly experienced with Crewe before joining Burton. Might be slightly out of reach budget-wise.
Jonny Maxted (29), Northampton - another one suggested, was backup keeper at Northampton last season. Was trialling with Newport recently, might come available.
Jonathan Mitchell (28), Doncaster - another one suggested, first choice at Donny last season but form was inconsistent and they chose to release. Might be too expensive.
Ryan Schofield (23), Huddersfield - former youth team mate of Isaac Marriott, and first team experience too. Been unfortunate with injuries and last seen on loan at Crawley.
Scott Moloney (22), Barrow - restricted mainly to EFL Trophy appearances, made one start due to injury. Spent time on loan at Guiseley but didn't seem to pull up trees there.
Mackenzie Chapman (20), Bolton - part of Bolton's 'B' team where Halifax found Adam Senior. Former United scholar, impressed on loan at Atherton keeping them in the NPL.
