Bob bro, Sport is not all about money, it's about passion and pride too. And yeah, you can win 4 MVP titles in NBA in 4 years, but just one gold in olympics. And if you talk about professionalism, Ronaldo, Zidane, Maradona didn't only played for their clubs for big money but also helped their countries to win world cup football titles. May be your so called "pro players" need to learn from them.
