This is not over!
I posit that other people will come forward and share information, now that the Gouchers, Magness, Stiner, and Kupcheck have come forward. I know that David Epstein has talked to several people who had information, but most were too scared of Nike to go on-the-record.
Furthermore, WADA will likely investigate the allegations. Because the situation is now worldwide news, WADA will reach out to USADA, people who were on-the-record, and seek more information. Further, they have a foundation to pursue acquisition of information regarding violations of anti-doping assistance rules - the IV drip, for example, that Kara Goucher mentioned, is a violation if his coach told him how to induce the medical personnel to administer the Drip at the World Championships. If true, that's at-minimum a 2-year ban by the coach. At most, it's a lifetime ban (doubtful that could happen, but it's possible if there is a number of other violations WADA uncovers, such as use of certain medicines without legitimate TUE, etc.)
And, let's not forget that David Epstein and Mark Daly are not the only investigative reporters out there who are hungry to generate a big story. The door is now wide open! I know of at least one (other) major news agency who is presently pursuing this PEDS situation with NOP further. I can say with confidence the organization plays to win! They are serious and they have resources. I am very excited to see this organization go after the truth, further!
I have told my family and close friends that I think Nike will have no choice, at some point, to throw Salazar under the bus. Nike cannot afford to lose credibility, and hence market share, from a business standpoint. Just as they had to let Lance Armstrong go, they will have to let Salazar go. I just cannot see how Nike will fight to the bitter end, for they will drag the company down in the process, even if they "win." Nike shareholders are not going to be happy about the loss of value that the media situation will create! The sooner Nike cuts ties with Salazar the better. If I were the CEO of Nike, I'd gather my executives and lawyers together, weekly, and hash out a legitimate strategy of dealing with the problem. I see no way that covering up for anything close to unethical practices is going to be perceived by the public, and especially the shareholders, as anything other than bad business.
As I see it, as one who had a Masters degree in Business Administration and who had studied many aspects of marketing, organizational management, and leadership, the smart strategy is revealing what you know to the public, before the fire is too big to control, as an organization. I estimate that Nike leaders were convinced by Mr. Salazar that the practices and methods he used were legitimate, though pushing the edge technologically.
If I were leading Nike, I would put into play an internal investigation, perhaps hiring an independent investigation team, and then make decisions based on the evidence gathered by that team. To me, it's a matter of saving the public image of the company, and that doesn't involve covering up information or delaying the process. The sooner the public image is bandaged the better!
