I kind of have to agree somewhat on this.
That effort, which was totally unnecessary(of course in hindsight, it was impressive when it happened, although I was puzzled at it even then) , clearly depleted a great fitness level, he looked completely ordinary at Millrose, no pop, no ability to move within the race, nothing.
I agree. My point would be:
Despite Salazar's contention that he learned from his past mistakes of training himself into the ground with non-stop intensity/volume, and despite the fact that I do believe he gives his guys more "easy" days, and breaks after seasons than he gave himself (some of the lessons he learned), I think he does push his people sometimes over the edge (in a different way: the Levins double, the insane post PR/AR/killer double workouts, etc). Now he can be somewhat forgiven for this considering the seemingly inhuman ability both Rupp and Levins have shown in the past in being able to withstand intense training, and then thrive off it. But, obviously, there is still always a limit to this . At some point, and I guess you never truly know when, you will brush up against, and then surpass, what is too much training for an individual. At some point it's too much. Who knows what Rupp was doing leading up to his bad race a week ago. With Levins, the really hard double with only 30 mins rest, with hard workout afterwards was likely the breaking point (and who knows what else they tried to pile on after that/during the week). You don't look that flat (as Levins did, or Rupp did last week) without either being terribly out of shape (certainly not the case with Levins), or being heavily overtrained (clearly Levins), at least short term.
Hopefully they all learn from this. If it's only a bad race, and then you bounce back great later, then obviously it doesn't matter a bit in the end. But if you overdo it a few too many training periods in a row....you end up like Salazar did. Injured and burnt to crisp.
