I don't think Doc is saying you have to be in a field to criticize it - I think he's saying it's a bit foolish to give much weight to the opinions of people who have no first hand experience with the field. I notice when this stuff comes up bloggers tend to read into it that they're being told to shut up somehow - they (usually) aren't - instead they're being told that they don't really know what they're talking about, they're full of sound and fury signifying nothing, as the man would say.
You are on the money fairweatherfan. I am almost certain this is a shot at Bill Simmons and I have a pretty good source that says the organization is not so keen on Simmons (not surprising in the least). In terms of Simmons' work related to the Celtics, I am not a fan either. I stopped reading him around the time his baby was born (not insinuating a correlation, just giving a sense of timing as to when I lost interest in what he had to say). Whatever problems Bill is having with ESPN right now, I hope he solves them, gets free of the four letter network, finds himself again, and asks for our forgiveness...
In terms of what Doc is saying with regard to bloggers, I'd say second to Peter May he has been the primary target of most of the negative press. I've always been a supporter of Doc and believe that, for the most part, he is a decent coach. Is he at the top of the list amongst his contemporaries? No, he's not, but talent wins in this league and he's proven to lead this team to much success this season despite many doubters on both local and national stage.
Doc knows I am credentialed through CelticsBlog and we have had a decent rapport. In doing the job you always remember that you are not making friends with the players and the coaches. You are friendly to them, they are generally friendly to you, but you are neither friends nor enemies. It's a business relationship.
Doc has a good point here, some opinions of him are unfounded. Ss it is with anything in life, the most extreme criticisms are usually wildly off base and unfair (enter BSG and the demands of the ESPN lifestyle). I think there are fair criticisms of Doc, including his ability to make in-game adjustments and some of his handling of the rotations depending on the circumstance. A counterargument for what can be seen as a weakness in terms of making those in-game adjustments is that he and his staff are conversely adept at making adjustments from game-to-game. I subscribe to the old sports cliche' that things are never as good as they seem and never as bad as they seem. However, if you remove the highs and lows from being a sports fan it is no longer any fun.
Doc has done nothing but treat me with a general sense of respect when I speak to him at the games. We're not friends, he may not even like me for all I know (or care), but as long as he treats me with respect - I doesn't matter to me either way.
Where Doc went wrong here was in making a distinction between writers and bloggers and placing the emphasis on bloggers as being the ones lacking the requisite knowledge to make an informed criticism. Many members of the traditional media have been as critical, if not more critical of Doc's abilities at times. The difference is related to the level of tact employed in making such criticisms and unrelated to the level of knowledge. There is one exception, and is what turned me off about Simmons doctrine on blogging, as there is most certainly an added benefit to having first hand knowledge of the team if you are covering them.
