It is not only Mets fans who hate this. Business Insider described it as “the worst contract in sports history”. Yet anyone with an economics training would shrug. As Planet Money points out, anyone who managed to invest $6mn at a 10 per cent rate of return in 1999 would have nearly $19mn by 2011. At that point, the investment pot would generate more than enough income to pay Bonilla his 25 annual instalments, leaving the principal sum to grow further. In other words, if the Mets could find a 10 per cent return on their money, they could shake hands with Bonilla, invest the $6mn, pay every penny of the $30mn they owe him, and have tens of millions of dollars left over in 2035 when the agreement expires.
