Props to Nadal for #22
As of now, Novak will go down #1 GOAT because he's the most accomplished and has records the other 2 dont. Most notably winning all masters at least once, and he's actually won every masters at least twice. Nadal and Fed both missing 2 masters and likely going to retire without them.
Fed will go down #2 in my eyes. Nadal having 22 slams doesnt make up for the fact he has ZERO ATP finals and is far far behind in weeks at #1. Nadal doesnt have a 05-06 FED or 11,15 Nole season. Nadal is worse on grass/hard than Fed/Nole on clay. Stans will say Rafa has an olympic gold but Fed has one too. Fed also has considerably more titles than the other two. Having no grass court masters really hurts Fed as he would have cleaned up house every year.
Novak 1, Fed 2, Rafa 3 unless Rafa wins another slam or 2.
