The only opportunity for major bucks is a gold medal and the many commercial endorsements that MAY follow. Conversely, tennis players complete weekly in international events and are paid big bucks for it, weekly. They have four major championships a year in addition to the annual Davis Cup competition, the premiere international event of the sport. Simply put, the Olympics should remain focused on the basics of athleticism, strength, power, agility, finesse. No racquets, no snow boards, no technology, just the human performance on a level playing field.
Tennis is a technological sport.
Baseball is not played in every country, either is basketball for that matter. The sponsors get their logo's on the tube 18-24 hours a day for two weeks. This takes absolutely nothing away from tennis or the Olympics. Our sport then fell from the Olympic venue after 1924 amid turmoil over where to draw the line between amateurism and professionalism, and it didn't return as a medal sport until 1988. It returned because the thin line between amateurism and professionalism had been methodically washed away by a new and progressive Olympic bureaucracy.
