Why are we struggling exactly? Have Killie or St Johnstone signed anyone yet? Nope. I doubt they're panicking yet. I believe we offered contracts to two Scottish based players, Ridgers and Stevenson.
Ridgers joined, Stevenson signed a 2 year deal with Thistle instead of a 1 year deal with us. Dundee and Hamilton have signed a couple of crocks and a couple of first division players. Should we be concerned by that?
As TC said, contracts of English players typically expire at the end of June. I expect the majority of our signings will be players who played in England last season along with a couple of loans. Therefore expect the first couple of weeks in July to be our busiest time with regards to incoming players.
