I read the article and it is truly sad, unhealthy and in the long run, not good for the sport. The lack of success by Michelle rests squarely on the shoulders of her parents and it is pathetic to read and hear about. I hope she can find some of the joy I saw on TV when she was 12 with that flowing beautiful swing. Also, Leadbetter should be the last resort for anyone who wants their kid to get better, what he has done to that swing is criminal.
You can go too far the other way too, not taking the proper steps to nurture talent and simply letting a child's talent fall by the wayside. There has to be balance in any healthy life. I agree with the poster that referenced Furyk and stated that incremental progress every year is a much better course of action.
Being a HS coach and teacher, I see both ends of the spectrum. I see parents that are delusional (in my area, this is especially true of baseball and softball) and rob their kids of participating in other activities and sports because they think their child is the next Chipper Jones/Olympic softball star. On the other end, I see kids that are talented whose parents do not have the interest to see them progress. Both cases are sad and a lot of the latter comes simply from how expensive it is to be competitive in any junior sport these days, parents parents of the former also have limited resources and often choose to put all their eggs in one basket, so to speak.
