There is a shift here. The topic was comparing Nadal with Borg, and I pointed out that Borg's Wimbledon record was superior to Nadal. Then someone jumped to Rosewall, forgetting the Nadal/Borg comparison. Two different topics. On clay, I would not rank Nadal above Rosewall, Trabert, or Hoad, or possibly Lendl. All of these players were overwhelming on clay, and the first three competed against each other to divide up the RG titles of the era. Nadal has had little serious competition on clay. Federer is not a natural clay player.
