I wish I remembered where I read this (I think maybe on profootballtalk): Every league has this and it's barely used because players believe it's not anonymous (even thought it's supposed to be). In other words, the owners will find out where you were, how drunk you were and who you were with, and use it against them in playing time and contract negotiations. That seems crazy to me, I was relatively poor in my 20s and still made bad decisions. Can't imagine what it's like to be these guys with all that money and time to burn.
