I would normally agree with you but he seemed desperate to get back closer to his family who did not settle in Scotland, I honestly think he would only have stayed here if it was one of the bigot brothers who wanted him.
I'm on the fence on the mulgrew issue but I can see why he might be in Bullens thoughts, potentially he could provide cover at LCB, LB and CDM, praying Frankie is fit to start on Saturday McAllister at CB and Hewitt at RB gives me the fear.
