"Actually Nicklaus won last in 1986 at the age of 46."
Cool.
Even better.
Proves my point even more.
It doesn't prove anything of the sort.
One cannot expect a tennis player to run around the court once he hits around 35.
If Federer ends up with the most grand slams ever, the case for him will be much stronger.
But, yes, Tiger will still be playing probably into his fifties, and be the all-time everything in golf. I favor Tiger now, but Roger too is dominant at his sport.
I personally don't think so.
However, Tiger is an amazing golfer and, barring serious injury, will eclipse Nicklaus as the best ever.
Similarly, I also think that Federer will retire as the best tennis player of all time.
