I don't think anyone is being negative. When Shoma broke up with his coaches, he said it was because he was no longer progressing. His jumps have not been stable in a long time and that does make Lambiel an odd choice. If all he needed was a supportive environment, why did he leave his lifelong coaches? Granted, this is all based on what we have been told. Who knows what really happened.
I wouldn't be surprised to see Shoma switch coaches again.
