The 1st, and biggest, sign to me that he's not a real coach is:
No matter WHO played or what they did on the ice, if the team WON he plays the same lineup. So if Weise is a -3, we're going to go ahead and roll him out again, because naturally, he helped us win. If a player played a good game and the team lost, he's still apt to be pulled from the lineup, because the team lost. These are the kind of moves you make based on superstition, like when you eat pizza before a game and don't eat anything else before any other games until you lose. A good coach looks at the matchups, the play of the lines, how things fit together and then decides what's needed to be the NEXT team.
The Neuvirth decision was stupid, but I will also say....this is year 2. This is his system now. In the 2nd year the players SHOULD be productive, fluent in the system and reacting quickly. If it's not working, it's not, because it's new, it's, because the players are sub par and the system itself is crap.
