Time To Question Dave Dombrowski?

So today is the day all the media has their reactionary pieces to easily the biggest deal of the Winter Meetings thus far (and likely to be the biggest one of the Winter Meetings once they conclude). This little nugget, via Ian, really, um, intrigued me:

The way I heard how the Granderson trade began was that Arizona was trying to get Edwin Jackson at the GM Meetings and was told Max Scherzer was too little of a return, but felt Scherzer and Daniel Schlereth was too much. So Diamondbacks GM Josh Byrnes' first call was to Cashman because he assumed Granderson fit the Yankees' needs so ideally, and that the Yanks had resources that Detroit wanted.

 Am I the only one that finds this concerning? I know this is going to come off as sounding like "the blogger knows more than the professional sports franchise" but I find this quote to be baffling. Max Scherzer isn't enough for Edwin Jackson? Is it that he strikes out more guys than Jackson? That he's younger and already had a better full season than Jackson's ever had? That he's cheaper? That he's farther away from arbitration? I'm failing to see where it is that Scherzer doesn't stack up with Edwin Jackson in the eyes of the Detroit Tigers.

I'm going to assume that the Tigers have a lot more information at their disposal than I do. I'm also going to assume that Dave Dombrowski can run a professional franchise better than I can. However, I do not follow the reasoning here.

What would a Scherzer-for-Jackson deal have meant?
