Well like I said neither one is winning the poll and D&W are only 4th. So I dont think they are overrated, even if some of the older teams might be underrated.
Still probably no team in history has had to face a rival that tough. Torvill & Dean faced a nowhere near prime Bestiamanova & Bukin, a baby Klimova & Ponomarenko, and Blumberg & Seibert at a time politics was heavily pro Euro and anti NA in both pairs and dance. Klimova & Ponomarenko faced the much hyped but technically deficient Duchensays, and the Russian understudies and also technically less advanced Usova & Zhulin. Grischuk & Platov faced up and coming Krylova & Ovsiannikov, baby Anissina & Peizerat, and Bourne & Kraatz. Pahkomova & Gorshov faced Moiseeva & Minenkov for only a year or two. Bestiamanova & Bukin faced Klimova & Ponomarenko, but the judges chose to make it no rivalry. K&P were nowhere near their 89-92 level of artistry and innovation anyway though (yet many felt they should have been consistently beating B&B even in 85-88 on their technical superiority alone). No team in history has had to meet the insane technical demands of V&M and D&W they have and delivered with such consistency and perfection time and time again.
