Theo Epstein and Jed Hoyer joined the Cubs in the fall of 2011 with a focus on rebuilding for the long-term.

Chicago's front office has accomplish that this offseason, while also improving for 2013.

"It's a line we're committed to walking," Hoyer said. "Our goal here is to build a consistently good team ... and hopefully a team that wins a championship. In order to do that, we're not going to sacrifice the future now for wins. But at the same time, every season is precious, and you never know when that team might catch lightning in a bottle. You never want to sacrifice that season entirely."

The Cubs have solidified their starting rotation and continue to add to a talented young core.
