I don't think it's correct to say that Nadal started "a bit cold." He didn't win Viña del Mar, losing in the final, but he went on to win everything he played except in another final to Djokovic in MC, through RG. No, he didn't win a Major out of the gate, but he came back refreshed and strong after a long lay-off, which was needed due to injury. That is the thing that is the same, and makes the example. It's not a Federer v. Nadal comparison. The guys taking the year off now aren't 34. They're younger. If they need an example of taking off 5-7 months to recharge the batteries and recovery from injury they have both Nadal and Federer as models. That's all I'm saying. If they need an example of trying to play through and losing even more time, they have del Potro, sadly.
