Carey when he signed for us full time was a huge let down. We waited and waited all summer and he showed up out of shape, struggling to keep pace and just couldn't get a run.
When it did finally come off, he showed flashes of brilliance but he was never good enough to play left back every week - Plymouth sorted this and turned him to a number 10 to fantastic effect.
If we were pursuing St. Johnstone's really lazy transfer policy - guys like Drey Wright, and Andy Considine, now Carey - I'd be having major concerns right now.
