the incredible display of ego around the comment about his picture being the best a Canon sports shooter could expect from it . . . Just a quick look around other reviews should have told him that others are not having the same difficulties he had and should have made him think again before hitting that publish button.
I think you've touched on the key here: so many photographers hold up their own personal experience (anecdotes) as examples of what can be done and what can't, what should be done and what should not, and forget that their personal experience may not match the experiences of others. While personal taste is appropriate for the artistic component of photography, it's more an exercise in engineering to decide how to use the equipment to collect the most and best data from each click of the shutter.
