Re: Crolla has only one decision to make...
He had to leave Arnie because he left Allegedly to go with Hatton.
If (and this is a big if) he or anyone else did decide to go with Nelson he wouldn't have to move to Scotland, he could simply do a month or six weeks up there. Not everyone gets three stone overweight and needs so long to get ready.
Of course there's nothing to stop Billy setting up a camp either side of Hadrian's Wall somewhere like McCracken does in Sheffield and inviting all comers.
