Nick,
I agree 100%, but there's no way the front office will push for it. It's bad enough they're as awful and underwhelming as they are when the new stadium was supposed to open up greater potential, but worse that they won't even try to go for it all in Mauer's prime. I've always believed they should win at least one title with Mauer and Morneau, and even after the (excruciating) disappointment of 2006 I figured they would have a good share of opportunities. I think when they blew it in 2010 that was a huge setback, and then the utter disaster of 2011 and Bill Smith's litany of bad moves threatened to kill the team for a long time. This year they've managed to find some life with the offense and bullpen, and Mauer's turnaround in particular is an important component of that. All they need to do in the offseason to compete is add at least two solid FA starters, maybe a weapon or two more in the bullpen, and shore up the infield if necessary (hoping the best for Plouffe in the long run). A WS run would probably require a little more, but I wouldn't object to making the effort. Ryan's offseason acquisitions (aside from Marquis) have worked out fine, so him ruling out free agency after this year doesn't make any sense.
That said, I think the team's likely headed for another stretch akin to the early 80's and late 90's. At least in the case of the former they were growing the foundation for the 87/91 teams, and the latter were just bad teams to begin with. A dry spell like that now would indeed be an injustice to the fans.
