A HC needs to be flexible. To adapt to changing situations whether it be during a game, practice or because of injuries. Not to be totally rigid, stubborn & refusing to make changes. I've seen this dog & pony show for nearly 5 years from O'Shea & I know I'm tired of it. Cal Murphy was a stubborn Irishman like O'Shea. The difference between the 2 is he won championships. Lots of them. When the situation called for it, he did show adaptation. He knew what it took as a coach to win. Our current HC is as flexible as a two by four after so many years & still hasn't figured it out.
