I have a couple of issues.
First, I don't really get the concern about the "vets" keeping out the kids. There is a competition process that seems to do a pretty good job of establishing who are the best medal candidates. I do understand the gripes about Michelle being able to bypass the process and get to the Olympics this year, in fact, I felt that way myself at first... until I remembered what her record has established. But anyhow, is that something that we have to worry about for 2010? No way will a 29 y.o. Michelle get a free pass again. And how likely is it that Sasha in three years will put together a Kwan-like record to earn that kind of pass, should she find herself injured at Nationals time? Thus, it seems the "olds leave, young rise" concern has little merit, IMO. If the kids can beat Sasha & co., great; if they can't, they probably shouldn't go to the Olympics.
Second, it bugs me that Sasha and Michelle are always lumped together in the old group. The 4-year age difference between them is huge in skater-years. A 21 y.o. has a lot more room for improvement than a 25 y.o., esp. considering that her main problem seems to be lack of strength (mental and physical). That is definitely remediable. That's not to say she will do it, but she has time. I just don't think their cases are all that equivalent. MK is way closer to the age when that will change from option to necessity than Sasha is. Anyway we have enough examples of elite, winning women in their mid-20s right now that putting pressure on a 21 y.o., especially a current Olympic silver medalist, to bow out just seems mean to me. For ABC there can only be one top lady, and the younger the better; but fans know there are ups and downs with all the skaters, and they should be able to respect more than one, and have a fairer sense of what a full career is.
I will say that I'm more sympathetic to the argument that if the vets don't retire, the pro circuit will shrivel up and die... but there's so little difference between eligible and pro now that I'm not sure that matters. Pro seems to be turning into the place where the late-20s skaters go - not an alternative to eligible for the young ones.
And yes, I'm a Sasha fan! I think I have self-disclosed that often enough but just in case....
