In terms of the right back situation I could see RS going for Elliot Omozusi who was released by Cambridge today, he played under RS during their play off run.
I think they had a top 5 budget but I don't recall them signing anyone for a large amount, they had a strong backbone with Flint and a goal threat in Wilbraham.
Ryan Iniss - 6ft 5 CB similar mould to Ben Turner and Reda Johnson, was on loan at Port Vale last season and I heard from one of their fans he was solid until he got injured.
