People like to blame a fully grown man, and not young men who are often not fully developed emotionally even when the young men are the responsible parties. If he's coaching in any matter like he did at SCSU, he's not asking players to go out and be thumpers; he wants guys who will play hard along the board to dig our pucks, in the slot to work for ugly goals, and just to generally beat their opponents to an open puck. Are the players doing that? If not, they either lack the motivation, the simple will, the right skills, or a combination of the three. From comments read, it looks like Motzko is questioning his players' collective will.
