Greetings,

Hi David - love your site. I'm curious where the "Baseball and Medicine" material comes from. It's reasonably accurate, but doesn't seem to have a good grasp of how diagnoses are made and the process that both teams and players go through. While the players have no incentive to reveal injuries, they have little disincentive to do so. With contracts structured as they are, with medical care completely at the whim of the player, and with injury not considered in arbitration, spending a season on the DL isn't as bad as it should be for the player. Where the player has an incentive is in preventing injuries before they occur. Once players realize this and are combined with an owner who sees players as an investment rather than a cost, some team will get a serious advantage. The A's are almost there and there are a couple others close behind.
