Paella Fatbutt is only 27. Wait for his percentage at 30, if he even plays at that age.
Even factoring the future, Rafa will have the best % amongst the current Top 4/
Roger has played 22 more Majors with 4 extra Titles . No way, Rafa will play for 5 more years and if he does, it will be because he will still be winning. If he plays 22 more Majors, he would accumulate 6-7 Titles. His ratio will be better than Roger.
Novak has played the same amount of Majors and has 6 Titles. Unless he goes on a unheard of and unrealistic Title spree at the Major Titles, Novak's ratio will be far lower than Rafa . Now and forever . Novak does not have that much years left to narrow the gap in Titles and the ratio with Rafa.
Murray is way down there , so need to discuss his chances AT THIS POINT.
