That Wayne Krivsky greeted Jon Heyman’s Adam Dunn rumor with a no comment might be taken by some as confirmation. After all, we have seen GMs deny similar rumors if the player wasn’t actually available. Then again, it may just be a blanket "no comment" on all trade rumors.
One interesting part of this Cincinnati Enquirer article was Krivsky saying that a 48-hour window could be granted to an acquiring team to hammer out a contract extension. Defense aside, Dunn’s impending free agency is the biggest drawback when comparing him to the also-available Mark Teixeira. But if Dunn is open to a reasonable extension at $12-14MM annually, that could even things out.
