Exactly - Craig Brown - Preston - Failure
Gary McAllister - Leeds - Failure
Jim Jeffries - Kilmarnock - Failure
All experienced coaches who have failed. Thats why the first two do not have jobs. Experience isn't the always the ansewer. Look at Barcelona, and b4 someone points out that he got promoted from th B team i know but that is the B team hardly experience to give him one of the biggest managerial jobs on the planet. Vialli and Gullit were reasonably successful at Chelsea and were inexperienced. Inexperience doesn't always mean that you are doomed.
However, I do agree that Gannon and Calderwood should be sounded out. If we can't afford them they say no what will we lose. As the saying goes 'you don't ask you don't get' .
