And, in furtherance of that, I don't think sportswriters would root for the Tigers to fail, because the Tigers failing isn't much of a story. Very few predicted that the Tigers would be where they are right now. Their triumph is the story.
As for the Reds...I'd be fairly annoyed if I was a Reds fan. They gave away two valuable young players that they could have built around(or, at the very least, traded for something better than a couple of middle relievers) because they grossly overestimated their chances at making the playoffs. A bad trade brought on by bad talent assessment. The NL Central is an awful division that will be up for grabs in the next year or two, and the Reds hurt their chances of being the team to take over.
