How to earn 71 million dollars a year
Become the Greatest Player of All Time, amassing 17 Grand Slams, holding the record for most weeks at No.1, win 80 ATP tour titles, endorse companies such as Nike, Mercedes-Benz, Rolex, Credit Suisse, Jura, Lindt, Wilson, and NetJets.
Remain classy on-court (e.g. no butt-picking or primal screaming), being elected ATP Tour Players' Council President, and know that your opponents are lessors.
Even in lean years, a 71 million dollar "salary" is possible
