I think the Shibutanis have not been 100 percent for quite a while, which has made it a challenge to get a lot of mileage out of these programs. If I was going to guess, I'd say they are at about 80 percent. I don't think it's because they don't want to train -- their work ethic is well-known -- but rather they have been able to unable to train the programs at the intensity that they would like.
To their credit they have not made any excuses. In fact, they didn't reveal Alex's injury at the end of the season until Champs Camp (and I feel it was a response to a question, not something they had disclosed voluntarily). I get the sense they're just doing the best they can through whatever struggles they are dealing with. I guess that's why I'm a fan, they seem willing to just work it out even if they're not always successful.
Of course Flattfan is right that sometimes you can work as hard as you can and you still won't get results, but I seriously hope that this is not a case of that, especially given their strong basics.
