The ranking system should only be based on Grand slams, instead it is based on how well you perform during the entire year and requires you to play often. I believe that this is because it helps tournament promoters make money. rankings should be based soley on the Grand slams and heres why: 1. In every other sport if you win the crowning event you are the world champion regardless of your record during the year. If you win the world series..who cares what your record was during the year. If you win the Stanley cup who gives a crap about your record during the year. Why should tennis be any different? 2. When Serena was kicking everybodys butt on the tour she was not ranked number one simply because she didnt play enough during the year. 3. When Sampras won his last US Open he was ranked like number 50 or something in the world....that was simply ridiculous! 4. The system promotes injuries. Playing that much tennis causes players to get hurt and shorten their careers. if you look at all the injuries on the tour compared to the old days you will see that there are far more injuries today even though medicine & physical training has improved today. 5. It causes great players to quit. I believe Sampras would have stayed in the game if the rankings were only based on Grand slams. If he could just show up for Grand slam events and still be ranked in the top 10 I think he would still be playing today. Bog quit Tennis at something like 26 years old for similar reason. He had taken some time off, and when he came back on the tour he was ranked so low that he actually had to qualify for tournaments. Instead he just chose to quit. The rukes shortened Borgs career, Sampras' career...who's next? 6. The current system takes away from the importance of the Grand Slams.
