In my opinion Pete Carroll is a good NFL coach, not great, but good. Is that enough to bring us to the promised land? With enough talent (thus a great GM, which I think we have) and smart coordinators surrounding him I do think it can be done.
Pete has proven to be a good motivator of young men. He has a great defensive mind and knows how to build a defense. From a scheme point of view, he may even be ahead of the game. From an energy and physical standpoint, he prepares his teams well for the most part each week.
However, this team consistently has way too many penalties. And penalties can cost you a game. This is a sign of an undisciplined team. His "excuse" is "youth", but I call BS. Tom Coughlin would never allow 7 freaking penalites in just the first quarter of a game, even with an all rookie squad. While being too much of a dicatator can be detrimental, in general, being a more disciplined team leads to more success IMO. There are exceptions like the Colts under Tony Dungy, but I don't get the sense that Pete demands the same level of respect that Dungy does when he walks into a players meeting room. Pete is simply too lax and "trusts" his players too much IMO. To truly be elite, I believe he needs to distance himself a bit more from his players. There needs to be more of a boss to worker mentality and less of an uncle to nephew feeling.
Additionally, I don't think anyone can argue that Carroll is not a below average in-game manager of the game. He wastes many challenges (one day which will cost us a game you can count on it) and tends to call at least one dumb "hormonal" play per game which makes you scratch your head.
Would I rather have Tom Coughlin, Jim Harbaugh, or Jeff Fisher? Hell yes, but it is what it is. Pete overall is a good coach, so I think we stick with him unless some strange massive collapse unfolds, but unlikely to happen. I do hope, however, that he recognizes his weaknesses and tries to make an earnest effort to correct them.
