I don't see a good coach at all. He only got the job with minimal experience effectively because of "nepotism".
I think despite all the negative criticism Jerry gets, I think he's hired the right front office people who've done well with personnel acquisition (with a few exceptions here an there), especially on the lines.
What I haven't witnessed is good coaching. I see superficiality: a focus on platitudes, cliches, politicking, clapping, "rah rah", and a process that has produced little to no progress. Political maneuvering is the way of those who can't really get the job done, and so essentially weasel their way around the system using superficialities to create the image that progress is being made.
Unfortunately for this team, as Parcells said many times: "you are what your record says you are."
