Yeah, but there's a HUGE gap between the top Junior pairs and the senior ones (much larger than the difference between Zhang and Rochette, for example). Also, junior pairs are allowed to compete in the GP, but none of them have medaled in it and none have competed at Senior Worlds. None of the teams have won this event before and come back. The only team to have won a medal is Iliushechkina/Maisuradze, who won the silver last year (in their first ever international event - like Nagasu in 2007).
