Re: On court coaching is crap
Sanchez's idiocy and total lack of class is a separate issue. Most coaches actually have a brain and some basic social skills. I think he or Nadia (after all, she signs his paycheck) should be hit with a code violation for this, it's completely out of line. Anyone who is amused by behaviour like this from an experienced tennis coach would find better value in watching Jerry Springer re-runs rather than tennis.
But yes, in general, on-court coaching is a stupid concept. Apart from anything else, it discriminates against players with English speaking coaches, because the opponent gets to hear every word of what is being said, whereas few will understand advice offered in Chinese or Czech. But that doesn't really matter that much, because the bottom line is that it doesn't really help players in the long run. It just turns them into lazy automatons who can't think for themselves on court, and who are completely clueless in slams where no coaching is allowed.
