I'm with you on Nadal. Bjorn Borg is a legend but how spoiled are we as tennis fans to be watching this current era with arguably the three greatest players to ever play Tennis all playing at the same time? Federer, Nadal, and Djokovic.... Remarkable.I'm watching The Last Dance series about Michael Jordan. I already voted for Walt "Clyde" Frazier as my favorite athlete but I may have to provide my top five. Jordan definitely among them. Bjorn Borg and Rafael Nadal would round out my top five.
I have no choice but to go with Wikipedia - Christy Mathewson. One of the original 5 inductees to the Baseball Hall of Fame, he dominated batters. The Giants won the 1905 World Series behind his 3 complete game shutouts where combined he only gave up 14 hits. He had a deep faith, refusing to pitch on Sundays to honor God. His service in WWI interrupted his baseball career, and his life too was shortened by a chemical warfare training accident.
Christy was a true gentleman, and as you can see in the picture at left, a member of our wet shaving community.
