Safin has such an interesting career. On one hand he's talked about in terms of "what could have been, but the thing is he actually had a fairly long career - his first to last Slam appearance spanning a dozen years. Also, despite having immense talent, a couple Slam titles and five Masters, he was also prone to go out early in Slams - look at how many first week exits he had. And then from 2006-09 he was basically a #20-60 player, yet played in almost every tournament. In other words, while he was consistent in his appearances, he seemed to have lost his elite talent yet still remained dangerous. In a way he was kind of a Youzhny or Benneteau in his latter years - never seeming to win anything, yet not the player you want to meet in the first week at a Slam.
