Now that Spain has defended their Davis Cup crown, it can be argued, that they have built up a dynasty in terms of successful Davis Cup teams. Looking back at tennis history, there were some great teams like the British team around the Dohertys or the Australasian team around Brookes and Wilding. I see the first real dynasty in the 20s with the US team of Tilden and Johnston, then the French Four Musceteers, then maybe the Brits with Perry, although they had no successor to Perry. The Aussies during the Hopman years had several dynasties, first the team around Sedgman, later that around Hoad and Rosewall, then that around Emerson and Laver. The US team led by Donald Dell in the late 60s and early 70s took advantage of the amateur-pro-split. McEnroe was the leader of a strong US team around 1980, but the team succumbed when he declined. In the 80s, the Swedes built up a real dynasty around Wilander, Edberg and Jarryd, later Svensson and others. Although the Germans, French, Russians and US had their share of wins in DC, they couldn't build up continued success over years. The great US generation of the 90s never committed fully to DC (with the exception of Agassi). Maybe some posters can share their thoughts of those teams and dynasties, can add some more teams, who are worth of mentioning, so that we could sharpen our criteria for Davis Cup success.
