Djokovic has passed Nadal with 155 weeks at #1 and is closing in on McEnroe (#5) who had 170 weeks at #1. Tops are Federer (302 weeks), Sampras, Lendl & Connors.

My favorite player is still Ken Rosewall , 8 grand slam wins. Born 11/2/34 exactly 10 years before me, 5'-7". Won the Australian Open at age 37 and was in the finals of the U.S. Open vs Connors at age 38. His slice backhand was the best of his era. (Connors reached the semifinals of the 1991 US Open at the age of 39)
