If Serena played Murray, Djokovic or Federer, she would most likely lose every single time. Serena (and her sister Venus) brought a new level of power and fitness to the game, which was miles ahead of anyone else in the women’s game at that time. Now take that against even a top 500 ranked male player, and it will fall short of natural strength and musculature, and 100 times the testosterone. Many women (and these knights in shining armor) are grossly under-estimating the difference in strength and power of men and women. Why are we getting upset with just the facts being stated?
