I spent too much time on this...I put together this table of players who left the Twins. I did not include numbers before they were a Twin (i.e. JJ Hardy). I also only used seasons with 150+ AB. I put together a couple charts, but they were just too hard to read due to the number of rows (21). The +# and -# are the number of years before and after the last year with Minnesota.So my conclusion, You can point to one or two examples that would prove either side of the argument. See Ortiz, David or Hardy, JJ. But also take a look at Orlando Hudson, Orlando Cabrara, or Torii Hunter. Also, there are any number of factors could explain the boost or drop in production outside of the players approach at the plate.I just don't see the smoking gun. What do you guys see?EDIT: I had to break up the posts due to character counts - I apologize for the multiple posts.
