As a Canadian who has observed the American Hype machine wreak its havoc on young athletes over the decades, I would have to say that Mr. Salazar may not be acting in his athletes' best interests. I think that publicly declaring that Kara Goucher was in world record shape may have predicated a choke.
I am going to guess that this reporter has been fed training information by Salazar rather than by Ritzenheim. The self-confidence of Haile, Kenenisa & Usain is considerably different than the external pressure of expectation applied by a coach.
Surely every single reader of these boards knows full well (even though optimistic & maybe patriotic as they may well be) that training times do not directly translate into performance times.
Obviously there is economic pressure on Salazar to get press for his athletes and himself to ensure continued funds. I admit it is an awkward position to be in. However, I think that a coach should be a little less noteworthy. Look at the caution that Renato Canova takes when he discusses future events. As for Haile & Kenenisa, I would not even know who is credited as their "coach" but even Jos Hermens - their agent - a previous world-record holding athlete himself manages to stay very much in the background to allow his athletes to establish their own positions in athletic history.
I may be entirely wrong ascribing the blame to Mr. Salazar. It could be journalists hiding around trackside looking for a story. But I think that revealing training results before an event is like a poker player flashing his cards - not strategically smart.
