I have not read this whole thread, I try to ignore Adam Dunn threads on the board for obvious reasons.
I hope I am not saying something someone else has said, but for me the main point about Adam Dunn has always been his defense. That is why the Reds did not sign him in the offseason (and why they didn't sign Abreu, Bradley or Burrell).
Dunn is having one of his best years offensively and he is still just a 1.7 win player the year when you factor in his defense. Chris Dickerson, the who the Reds planned to replace Dunn with this seaon, is currently a 1.4 win player when you factor in defense.
It is very simple. They get nearly the same production from Dickerson as they would get from Dunn, at 1/20th the cost.
I have no idea if Dunn wanted to be a Red, but it is a moot point, because the Reds never wanted him, and for good reason. Dunn is one of my favorite players, but even with his "bargain" contract of $20M for ywo years, he is overpriced, when you factor in his defense. That is why Dunn is not a Red.
