Gotta be Laddie Burger.
Speaking of... I had an epiphany today. I don't know why it took me so long to see this, but I finally understand why Blurger hates Adam Dunn. More importantly, I understand why he doesn't like Mike Morse (at least not at 1B). It doesn't have anything to do with Adam Dunn or Mike Morse - it has to do with who can make his hero Ean Desmond look good. Above-average to good 1B's like LaRoche can hide some of Ean's errors. Average to below average 1B's like Morse and Dunn cannot.
It's ALL about Desmond.
Not sure why it took me so long to realize this, but I am now convinced that's what it all boils down to.
