Mort is only a young lad though, he only broke into the Leigh first team during last season, we may have identified that he has potential. Hardman is a very solid and reliable player but doesn't offer the attacking threat and pace of an exciting attacking style full back.
I also read in League Express that Barrow wanted Grayshon but he chose Widnes instead so that was good news.
Hardman's only 23, hardly old himself. Mort would be a backwards, or at best a sidewards, step.
