I think that people have forgotten how hard it is for teams to transition from junior to senior - unless you have a truly exceptional team like V/M, it's super hard and was very rare before 2010 for a team to go senior and straight away start medaling on the GP or hit top 10 at Worlds. You see it with the Parsons and M/C and L/D this year, even though in juniors they were getting very high marks - there is so much more expected of you, particularly in presentation, in seniors.
There was an oddity in 2010 with the Shibs getting on the podium and I/K having a top 5 at Euros and top 10 at Worlds - but you have to think about how many teams had quit or were missing; Russia lost Domnina/Shabalin and Khoklova/Novitsky earlier than they would have anticipated, V/M were out for much of the year, as were the Kerrs and Cappellini/Lannotte, Scali/Faiella stopped their season in the middle of Euros, and then P/B made the huge mistake at Worlds. The more experienced top teams were decimated that year due to factors beyond their control, which allowed the younger teams to break through, but I think people have begun to think that should be the norm, when really it was an exception.
If Russia is really serious about rebuilding it's ice dance program, it has to give teams like Skoptova/Aleshin, Shevchenko/Eremenko and Polishchuk/Vahknov time when they move into seniors. They won't set the world alight straight away, but they have a lot of potential, if it's nurtured properly. There is no point in partner swaps or coaching changes if it's just to be the 5th priority for Igor or Marina. The one thing I think they should be doing is turning senior a little earlier - L/D could have done it last year, and I think would have learned more than they did doing a 4th junior season. When I saw them at JGPF last year I thought they had stagnated compared to when I'd watched them in Barcelona the year before - they needed to keep stretching themselves, and if they had, and got their heads round the expectations for seniors, they could have been in the mix with Z/G for that surprise bronze medal.
