Indeed.
I'm not worried about the jumps - I remember Liza at this time last year, at one of these competitions, and look at her later. As for the quad, Papa Mishin will no doubt have him put it in when he thinks he's ready for it.
That said, I do think we should prepare ourselves for the eventuality that this might turn out to be something of a transitional season for Sasha, and that, therefore, everything might not be as smooth sailing as we'd all wish. He's moving up into seniors, he may be experiencing some growing pains perhaps, and then integrating the quad. But, in spite of all that, I'm not worried. He'll get through it just fine, I'm certain.
