It's interesting to see a thread where much of letsrun seems legitimately concerned about Webb and the discussion has remained civil and (almost) constructive.
I am a big fan of Webb and like most people here I really hope he gets his sh!t together. I think it's been mentioned on this thread, and I think there is a lot of truth to the saying "the definition of insanity is doing the same thing over and over again and expecting different results." Over the past few years I thought the calls for Webb to switch coaches were ridiculous, as Rackzo got him to 1:43/3:30/13:10/27:35, but it is clear that his program is not working anymore. I think switching coaches could only be a positive thing now.
The suggestion that whatever he did to grow hair back could have messed with his hormones is frightening. Didn't Ryan Hall blame accutane for his poor performances for a while? The brojos are right that he should get his blood checked.
Obviously there is the mental aspect, something it's impossible for most of us to know enough about. By definition, runners are only in shape to run their PRs once in their lifetime (when they actually run them); it's such a difficult thing to do, and obviously the best (Lagat, El G, Geb, Coe, Kipketer, etc) are the best not only because of their PRs but because of their ability to get in near-PR shape at least once a year. Others (Ryun, Khannouchi, Komen, Ngeny) had the PRs but not the consistency/longevity of the legends. It's frustrating to think that Webb (and all of us) might just have to accept that he is in the latter group.
Apologies for the lack of new insight, but I wanted to keep this thread going.
