I was all set to point out that Billy Beane has indeed had previous interest in John Maine, but MetsBlog and a lot of message boards beat me to the punch. That’s what I get for taking the afternoon off.
For what it’s worth, I did find this Peter Gammons article from December of 2004 mentioning that Maine was offered by the Orioles for Tim Hudson along with Erik Bedard and Hayden Penn. Man, why didn’t Billy Beane take that offer? That’s 3/5 of a starting rotation right there.
