I think its fairly well known that he is a useless game day coach and is regarded as the easiest coach for opposition coaches to coach against because he is a one trick pony who doesn't make changes and cant respond to what the opposition are doing.Oh I agree with that. I was more referring to the change week to week in terms of game style.
Travis Boak was interviewed on ESPN's website earlier this year in a multi part series where he discussed game plan and what not. He was saying that Ken doesn't really make changes during the game and tends to let the players just try to execute the style trained during the week. That premise made me worried then and it still makes me concerned now.
