...the ONLY thing mentioned in an official press release about the reasons for Sasha's change was the "TT didn't think she should skate in the Michigan comp" due to an illness.
I'm not buying that as a skating fan - maybe that's all there is but I suspect a coaching change decision would require more factors than that.
By the same token I've read here and on other boards speculation about needing improvement on jumps, TT's health, Sasha's mental ability to deal with compeition, and many other things. Since I've seen none of those things quoted in valid news reports from Sasha or TT, I discount all of it.
We may or may not ever know why this decision was *really* made, but speculating just gets crazy at some point.
I will wait patiently to see what the results are of this change - and Nationals will be our first view of that on the ice.
