If you are interested, there are a few responses posted to my proposal for removing performance-enhancing drugs from baseball published in Saturday’s New York Times. I further explain my proposal here.
The main complaint is that players will not be willing to rat out one another. I agree that there may be few instances of players selling out specific teammates—though, it seemed to be enough for Judas. My comment that players would have an incentive to police each other was more about players identifying new drugs and methods deception employed by users, which clean players could pass along to the union in order to strengthen enforcement, than squealing. I did not explicitly state this, and I accept the criticism
My proposal is merely a proposal. Though I am nearly certain that what I have suggested will not be a part of a new system, I hope that planners will pay careful attention to the incentives I discuss when they design a new program.
