excellent points general tented.
the sport really needs all big 4 to be healthy, fit, and ready for 2014.
Federer is not an ordinary 32 year old. he has some weapons which others cannot boast.
and he has all that variety.
we may even have the big 5 now. del potro is coming on strong as he showed us this year.
at any rate I am expecting Federer to do significantly better in 2014 which should delight his fans across the globe.
