The Cubs last year had the 5th best record in the league and the 3rd best run differential. It sucks that they shared a division with the team 1st in both, but by basically any objective measure they were shoulder to shoulder with the rest of the league's upper crust.
They did this with a backdrop of stellar player development. They had rookies develop into first division types at SP (Horton), 3B (Shaw), and Closer (Palencia, and I know he wasn't *technically* a rookie). Two of their fun rookies from last year, Busch and PCA, leveled up significantly. Moises Ballesteros had a stellar cup of coffee and is one of the favorites for NL ROY next year.
This fanbase goes insane when the wind blows in so the vibes were pretty crappy most of the year, but this was a very successful season both in isolation and in setting up for subsequent years. There's very few years where if you offered me 92 wins and three rookies move into the core that I'd choose to re-roll the dice.
