He said he started working with him in 93. 1993- 09/10 is a very long time to be with the same coach for,especially when someone has gone from teenage to mid 30s a lot can change in them so that they may not exactly see things the same way the did. Anybody would be expected to feel the need to "break free" so to speak, from someone who has pretty much been in charge of their life for so long. Whether the decision was right or wrong and the way it was done is another story but looking at someone at the ages 16 and then 37, I personally wouldn't expect them to see things in the same light.
