Did Davis ever claim to know how to use this stuff or say he does use it?
No, he just uses his name and world-class athletic ability to get on the stage as an "equal" with someone who does.
Can't coaches just give workout plans that are designed for their runners without knowing their exact VO2 max?[/quote]
And compete with the rest of the world now? No.
And anyone who thinks coaching recreational runners is Davis goal doesn't know Davis very well. He'll take whatever his athletic name can get him regardless of whether or not he's qualified for a position. A big clue is in my thread "The DOC is a quack", whrein davis mentions getting a USATF certificate and he would then be qualified to coach a national team, if he wants. (And he would want.)
Such aims are fine if they are backed up by the education and training to earn them. Not so fine if they are sought by taking the easy path of using name and celebrity.
People like me are tired of seeing the embracing of mediocrity in this country by qualified people getting passed up for leadership positions so those positions can be charitably given out to unproven "stars." The American Love of Celebrity erroneously gives a person who achieves competency in one discipline automatic status and position in a second discipline simply because of who they are and that they ask for it. That's wrong, and Davis is a shining example of that perverse ideal.
