Nowhere did he says he "likes Willingham." He said he has "mixed emotions" on Willingham - hardly a ringing endorsement.
It is quite the leap to assume that he hates Dunn based upon the fact that he wishes the Nationals to trade him to the American League. By that logic, I "hate" Willingham, and that couldn't be farther from the truth.
If you should attack anything, it's Ladson's rather asinine implication that Dunn's offensive contributions are completely offset by his deficiencies. Making a simplistic "hates Dunn, likes Willingham" declaration is feeble.
