This is really quite a silly poll. Without knowing what total revenues are, both those of individual teams and those that are shared (revenue sharing, licensing, visiting team shares of gate receipts, national media), as well as expenditures, no one here can begin to suggest a dollar amount.
Certainly the teams are entitled to a reasonable profit, but without seeing the numbers, no one here can reasonably suggest how much should be spent on payroll.
Several years ago, in one of his books, Roger Kahn published a simplified balance sheet for the Brooklyn Dodgers of 1953. I forget the numbers, but three things stick out in my mind. Revenues were approximately $5,000,000, payroll was approximately $400,000, profit was approximately $3,000,000. After exploiting the players for 100 years, free from the restraints of trade to which other businesses are subject, the owners got what was coming to them with the advent of free agency.
