We often see top ranked Djokovic on men's side or top ranked Williams on women's side in the finals and to be sure they could be the best right now and maybe even ever. I don't think I have seen a men's player or a women's player with the weapons and sheer stamina and mental toughness of these two. Williams has no equal or at least since Steffi Graf days way back when and Steffi had at least Seles who had her number at times, but Williams never had anybody dominate her other than her older sister when they were very young. And while there are great #2, #3, #4, and #5 seeds on the men's side this year, Djokovic is further ahead this year than any former #1 was over their best competition at any time in tennis history (Novak at 13,845 to #2 Federer's 9665 points as well as being first man ever to win first three Masters 1000 tournaments): http://www.marketwatch.com/story/world-no-1-novak-djokovic-sets-two-records-2015-04-20 But interestingly, while Djokovic easily beats his opponents he can often beat himself in Semi-finals and Finals with inconsistency, and he is in Quarter Finals and does face the highest ranked challenger in #9 Cilic. Others in Quarters are #4 Wawrinka vs #21, #3 Murray vs. an unseeded player, and #2 Federer vs #12. And Djokovic is the defending Wimbledon champion of last year and he could down Fenderer like last year and is 11 for 16 against him since turning #1, beat Murray like many times before and is 15 for 20 in that rivalry since hitting top spot, and certainly won't fall for and hit clay dampened shots to Wawrinka's backhands like the French Open and beat him 9 for 11 since number #1. If Williams makes it to final, she will only have to face #13 or #20 seed, but she still has to get past #4 Maria Sharapova in the Semi Finals which is the highest seeded match thus far at Wimbledon on women's side. Williams is coming off of rather recent wins at French and Australian Opens so I expect her to be at her peak. But when Sharapova is on, like these days and when she first rose to prominence, she can challenge Williams. Williams at 33 can't keep it up forever and Sharapova is five years younger and rivalry which has been mostly Williams, will change if Williams stays in tennis much longer. While I expect several more majors for both Djokovic and Williams, things could get very interesting if both #1 seeds fall in their next matchups. This type of possibility, which seems possible with seeds remaining and who is facing the two #1 players next, and is why I love tennis at times.
