HOW COME AN OUT OF WORK MANAGER LANDS 5 YEAR CONTRACT?

Forgive me if I appear stupid!Been trying to work out if Newcastle is such a great club as they all tell us ,how an out of work manager becomes Newcastle's eighth manager in five and a half years and gets a contract for that length of time.I like Alan Pardew and I hope( that's all I can give him)
he does well but his last four jobs have been Reading,West Ham,Charlton,and Southampton.He was poached by West Ham who,together with Charlton and Southampton went on to sack him.Most people in his position would have snapped Newcastle's hand off.Give Pardew his credit,he argued hard for a five and a half year contract.Well done,Alan..but more fool Newcastle.The sacking of Chris Hughton was terrible.I never saw him more than an outstanding number
two but give him his due-the got Newcastle promoted back in style and they were 11th in the Premier when he unfairly got the boot at the weekend.Owner Mike Ashley will either get his just desserts if this does not work out of the fickle fans will quickly forgive him if Pardew puts together a string of wins.That's the nature of the beast..............
