2011 may have seemed like it lasted for about 4 years, but it was actually only 1.
Unless you spent 2008-2010 watching replays of the 2007 season, I don't see how you could characterize the Twins as lifeless for the "last few years".
I think the whole "Heart" thing gets overplayed. There's often this knee-jerk explanation for sports outcomes that it all comes down to the victor having a greater desire to win. I'm sorry, but I don't buy the idea that reality is that close to Rocky movies, and it's all about who has the "eye of the tiger" and other factors (talent, injuries, matchups, luck, bad calls, bad decisions, weather, scheduling) have no impact at all.
