I don't think he will be considered by Grimsby, he has no league experience,he has spent his whole career in non league.
He most probably doesn't even have any league contact's, Grimsby need someone who has contact's and experience as the are in a very bad position and will not want to go down.
I don't see them taking a gamble on someone like Craig, my money is on Phil Brown.
Craig also has a career outside of football, which he probably doesn't want to give up just yet.
Let's not forget that we are not far off league football in the pyramid, no doubt David Newton would love the club to be back there, and who would bet against Craig taking us there anyway.
I agree with Ted, the club need to clear this up ASAP, before it starts to affect the players and our current form, uncertainty is not a positive.
