I believe there are good coaches, bad coaches, and average coaches. But I also believe there are coaches that are so far ahead of the rest, you'd be stupid not to hire them. I don't think Lovie is a bad coach, I think he's an average one. With a good team, he can get them to play as one and succeed. However on a bad team, or a team that is falling apart, or needs a schematic advantage to compete with more talented teams, he fails miserably. But Cower is someone who is one of those superior top of the line coaches. When you have an opportunity to hire a coach like that, you have to get him. If you can hire a coach that can consistently produce results at or above their talent level, a coach that can outscheme the opposing coach most games, a coach that can make successful adjustments on the fly, you have to. Coaches can affect a teams play. But only the creme of the crop can do that with any consistency.
