His excuse for not releasing those plans already will be that the vast majority of his paying customers were totally happy that he didn't. And sadly still are. Thats why he's been given such an easy ride. Even now, a fan fair announcement as to what the plans are (if good) would definitely boost season ticket sales. Perhaps thats what he intends to do very imminently. I doubt it though!
You're right, Drilling about too many wanting, one way or another, to believe in KT but when you stand back and consider his time here I don't think it will be remembered with any great affection. I am convinced he will be gone before long because he has run out of road.
