Ferrer is born in 1982 but he's consistent in the top since 2005-2006 only, while Roddick, despite being born the same year, is a force since 2001-2002.
Raonic is in the scene since a few months while Djokovic has many more miles in the legs.
2012 Raonic is comparable with 2006 Djokovic. Djokovic is only 3 years older (note that Raonic is born in december) but he has played 6 more years than Rao.
But again - add to this that players of Rao`s style are injury prone. It will be miraсle if he plays next 7-8 years without missing important tournaments here and there, it never happened in past. Actually even Milos has such experience already.
