Lol, I forgot he missed Wimbledon last year. So that's two majors he had to either withdraw from or miss entirely, before shutting down the season early, and you're seriously arguing he was "mostly healthy"?
I don't care if he would have gotten his ass kicked. Nobody's saying he would have won if he played. I'm saying he obviously was not close to relatively healthy last year. TWO freaking majors. Are you seriously ignoring that these injuries mean taking time off and having to recover, working extra hard to regain fitness AND struggling to rediscover your level? So Nadal would have lost to Djokovic at RG, lost to a nobody at Wimbledon, and lost to anyone in the fall so the injuries don't matter... that's your argument, while ignoring everything else that comes with injuries in terms of mental and physical stress, lack of confidence, etc...
