Anyone interested in sports photography at the Olympics can currently find it on the Jeff Cable's blog lots of interesting pictures and background information. I think it's particularly good that a lone fighter writes here and not a photographer from the usual agencies. They have a completely different infrastructure. At Getty, for example, the JPGs are sent out of cam via kilometer-long Ethernet cables directly from the camera to three editors. Of the three, one selects the appropriate images, one does the image editing and one labels the images with the correct metadata. This is of course a completely different kind of work than most of us can imagine. But the agencies are also under a lot of pressure that couldn't be handled otherwise. It takes around three minutes for an image of an event to reach the editorial servers of the news products and be processed there to create the latest news. Around 2000 images of current sporting events are sent around the globe every day.
There is also a stylish app from Getty (for example at iTunes) where you can see for yourself how fast the service is. The app provides the images from Sochi almost in real time. Just search for "Olympia"...
Of course, Jeff Cable doesn't have these options. And he also writes very sympathetically about his mistakes, because of course he can't capture all sports perfectly photographically right away. Nobody can do that. It's all the better that he doesn't pretend to have the appropriate skills, but rather writes about the considerations and attitudes with which he made progress towards the goal of taking a good picture.
By the way, it's not uncommon for him to be on his feet for 18 hours for his work as a sports photographer. The fact that he takes the time to blog is even more appreciated.
