And since you think 'there is a legitimate spotlight to shine on Salazar's athletes' you agree with the idea that they are questionable. You seem hopelessly confused. So I will leave you unless we can move onto something more substantive.
I think it rather depends on what substances Salazar has been dealing with - if it's something with a short metabolic life then the confidence interval of periodic testing might be low enough that there are serious questions. If that were the case, you'd like to think it would have been mentioned, but I can understand that perhaps WADA doesn't want to do anything that might call into question its own capabilities and processes.
Unfortunately, to an extent, there's always a question about the validity of any successful athlete these days, purely because it's an area of human endeavour in which the arms race between dopers and the authorities has been so well-documented and so extensive and so clear for such an extended period of time.
There's nothing in the evidence, I know, and I genuinely like the guy, but I find I can't help but look at Usain Bolt's record (for instance) and the Jamaican sprinters of that era in general, and think that it feels like something weird was going on.
