Speedy winger Jack Stobbs, 27, stepped out on his career with Sheffield Wednesday and was with Torquay United most recently after spells at Grantham Town and Oldham Athletic, being a regular in League Two and the National League.
Full-back Josh Williams, meanwhile, began his career at Aston Villa’s academy before then being a second year pro at Crystal Palace. He then moved on to Luton Town where he got first team experience before spending last season at Hemel Hempstead Town in the National League South.
The moves emphasise the benefits of shifting to full-time football ahead of the new season, with several other players with full-time experience having also signed for the club in recent weeks following McGrath’s appointment.
