pedrocerrano already has his Hall, so I'll go ahead and take:
Dick Hall, 1955 Pirates, 2,224,932
Back in the 3rd round I drafted an $875K Blair. There was a version available that was about $400K cheaper, but the version I took had a teammate that I was convinced that I would want to use. Now I'm probably not going to use that teammate, and the way things are shaping up that extra $400K might very well prevent me from filling out my roster the way I want to. Just another example of why I both love and loathe this theme.
