Well, imo, we`re experiencing the old conflict of insight vs. overviewing (right term? bare with me)
Doc is the insight. He knows much more about any detail concerning the team and ultimately his job than anyone else. But this also means he is caught in his job, his life as a NBA coach. He looks from the inside out.
The Blogs are the voice of the bystanders, the people who can only see the whole appearance. It´s much easier for us to come to absolute conclusions, especially about the general direction things take. But we don´t have enough insight to rightfully point to a reason for this direction. We´re looking from the outside in.
An example:
I earn my money with music. Let´s say I write a song which I love, I`m convinced, I know I did a great job, study it with my band and play it at a concert. The people hate it, and they start to feel annoyed and some people even boo me.
Who`s right? Me, who actually wrote this song and is convinced it´s the best thing I´ve ever done, who spent his life to master the art of songwriting? Or the people, although most of them can`t play a music instrument?
I can`t tell you. All I know is that if I continue to turn the people off, I won´t play any concerts at all in the future. Although I might be completely right and wrote a brilliant song, I have to listen to the people. I am the one who has to change, cause they won`t, they only judge, and it won`t help me to criticize the people for judging me. In fact, it is a big part of my job to listen to exactly these people and to take their opinion into consideration. If I stop doing this, I´m bound to fail.
Another example, a different angle:
I am a big movie fan. 5 years ago, I had to listen to all kinds of people from the industry (critics, directors, actors, producers, journalists, etc). It was the only way to inform myself about new movies, and to find out which movie I want to see and which not. There were a lot of good movies I´ve missed, and I saw even more crappy movies. For whatever reason (PR, personal agendas, bias), I couldn`t trust the information I had.
Nowadays, I go to IMDB.com (I hope it´s ok to mention it here).
Tons of people feel the need to post reviews about the movies they have seen. Although some think one movie is excellent, and others think the same movie is boring and makes no sense, I just have to read enough reviews and I pretty accurately know what to expect. I can honestly say that the quality of the time I´ve spent on movies increased dramatically since I visit this site.
Do the guys who post their reviews there know more about movies than the guy who directed it? I don`t think so, but I trust their opinion a lot more, and I have good reasons to do so...
