Arizona Diamondbacks

The Diamondbacks surprised everyone by going all-in on this offseason, but from a certain point of view, their gambit makes sense. They had to give up prospects -- lots of them -- but they added to a team with a serious core including Paul Goldschmidt and A.J. Pollock in the hopes of winning while they still have them around. At a time when so many teams are taking steps back for years at a time in order for a chance to win, a team risking the same but in the opposite order shouldn't receive so much criticism. In theory, anyway: the D-Backs still have to hope what they did was enough to justify their plan, as they might have stopped short.

Key Addition

Zack Greinke was stolen away from two NL West opponents in one move, as the Dodgers previously had the right-hander and the Giants were supposedly close to signing him. Not only that, but he gives the D-Backs a legitimate ace, and acts as part of the justification for the major Shelby Miller trade that followed.

All additions: Zack Greinke, Shelby Miller, Jean Segura, Tyler Clippard

Key Departure

Ender Inciarte was part of the Shelby Miller price tag, and he could very well be better than Yasmany Tomas, who is set to replace him in Arizona. Inciarte's defense gives him an edge, but his bat has been good, too, so the Diamondbacks have to hope Miller is worth it.

All departures: Ender Inciarte, Dansby Swanson, David Hernandez, Aaron Hill,

Best Case

The D-Backs built themselves to go for it, and with Zack Greinke and Shelby Miller added to a team that already had Paul Goldschmidt, Patrick Corbin, and A.J. Pollock, they succeed by winning the NL West. There is enough star power to overcome some of the depth questions on the roster, in large part because of the job the revamped rotation is able to do with Greinke at its head.

Worst Case

The Diamondbacks could easily become the 2013 Blue Jays, 2014 Royals, or 2015 Padres. Those teams all made huge moves and came away looking like offseason winners due to the size of their deals, but they didn't do enough to solve their issues with depth, and they didn't succeed. At first, anyway: both the Jays and Royals eventually made good on their early moves by making more of them, but as the Padres' 2016 reminds, not every team is built to keep adding after the initial burst, either.

Projected Team

Lineup: Jean Segura, A.J. Pollock, Paul Goldschmidt, David Peralta, Wellington Castillo, Yasmany Tomas, Jake Lamb, Nick Ahmed
