We will need a few from the end of contract list, it is after all how we acquired the following (and I stand to be corrected),
Marosi, McFadz, Allen, Dabo, O'Hare, Pask, Rose, Kelly and Wilson*
It was noticable that last summer we got nobody that way, whereas the nucleus of the promotion side came from out of contract players. If we are getting OOC players, better they are from the Championship
The other source would be sell Hamer or O'Hare and buy top performing players in League 1.
* Someone, probably Grendel, will chip in now and say Wilson cost us a chip butty, or Dabo a dutch bagel, so doesn't strictly speaking count as a free, or similar.
