I disagree with you that everything would have worked out between Orser and Adam. There were underlying differences in personality and expectations. It's not a negative slant on either Adam or Orser. I'm sure they both learned and grew from the experience. As far as whether the split was strictly about off-ice training issues, I doubt it. Frankly, it's easy to spin reasons after-the-fact. I don't recall what if anything Adam ever said publicly about that coaching relationship. And it's certainly water under the bridge by now.
It's clearly easy for you to talk about a figure skater 'wasting years jumping from coach to coach.'

No experience, not even failure, is ever a waste if something is learned. See my previous post on this topic. Adam was not a frenetic 'coach-swapper.' And that label is too easily lodged against figure skaters, almost as freely as fans braying after every competition that so-and-so needs to leave their coach and go to another coach.
The bottom line for everyone, not just athletes, is to learn from every experience in order to make better choices, and to not stay in a situation that isn't working.
