I wouldn't say that there are too many clay tournaments in the calendar, but the scheduling of them could do with a rethink. In particular, having three or four weeks' worth of optional clay events after Wimbledon is ridiculous when it makes far more sense to transition from clay to grass to hardcourt. And I think many players in the past who were labelled mere clay-courters are coming into their own on faster surfaces, earning their higher ranking. True, the likes of Felix Mantilla would not be in the Top 20 were it not for their exceptional results on clay, but take the example of Coria, who has gained the most points on clay of anyone in the Top 10 - he still reached the last 16 at the first three big hardcourt events of the year, the AO, Indian Wells and Miami. As Hewitt said in an interview last year, the bottom line is that for the top players, hardcourt tennis constitutes a good three quarters of the year, so that's really the dominant surface in the men's game.
