Dodgers have the swag, but others reloaded Rating the N.L. West

2.Arizona Diamondbacks

Last year: 104-58 (lost World Series to Houston Astros)

Key losses: Yu Darvish, Curtis Granderson, Andre Ethier, Tony Watson, Adrian Gonzalez, Scott Kazmir, Brandon McCarthy, Charlie Culberson, Luis Avilan

Key newcomers: Matt Kemp, Tom Koehler

Best-case scenario: The Dodgers come back reloaded and healthy. Kemp overachieves and becomes either a trade chip or a postseason asset, Clayton Kershaw wins another Cy Young, and Corey Seager and/or Cody Bellinger vie for MVP.

Worst-case scenario: Some of the moves to shed salary result in the shedding of valuable depth.

Hot prospect: Walker Buehler is one of the top pitching prospects in baseball. Pitching coach Rick Honeycutt could turn Buehler into a Rookie of the Year candidate.

3.ColoradoRockies

Last year: 87-75, third place (lost to Arizona in wild-card game)

5.SanDiegoPadres

Last year: 71-91, fourth place

4.SanFrancisco Giants

Last year: 93-69 (lost to Dodgers in NLDS)

Key losses: J.D. Martinez, Fernando Rodney

Key newcomers: Alex Avila

Best-case scenario: Robbie Ray turns into one of the most overqualified No. 2 starters in baseball and Paul Goldschmidt again shows his MVP form.

Worst-case scenario: A massive power void is left with the departure of Martinez.

Hot prospect: After the trade of pitcher Anthony Banda, right-hander Jon Duplantier is Arizona’s only player on Baseball America’s top 100 prospects list. And he finished last year in high Class A.

Key losses: Carlos Gonzalez, Tyler Chatwood, Jonathan Lucroy, Mark Reynolds, Pat Neshek, Greg Holland

Key newcomers: Wade Davis, Bryan Shaw, Chris Ianetta

Best-case scenario: The addition of Davis and Shaw fortify the bullpen, and Nolan Arenado and Charlie Blackmon again are MVP candidates.

Worst-case scenario: The Rockies pitching staff takes a step back, and the lineup continues to struggle.

Hot prospect: The Rockies might have found a first baseman in Ryan McMahon.

Key losses: Yangervis Solarte, Ryan Schimpf, Travis Wood, Erick Aybar, Jhoulys Chacin

Key newcomers: Eric Hosmer, Kazuhisa Makita, Craig Stammen, Freddy Galvis

Best-case scenario: Hosmer proves worthy of his eight-year, $144 million free-agent contract, and some of the Padres’ young prospects produce.

Worst-case scenario: Hosmer isn’t enough to ignite the offense.

Hot prospect: Former first-round draft pick Cal Quantrill could crack the rotation.

Last year: 64-98, fifth place

Key losses: Denard Span, Matt Moore, Michael Morse

Key newcomers: Evan Longoria, Andrew McCutchen, Tony Watson, Austin Jackson

Best-case scenario: Longoria and McCutchen ignite the offense.

Worst-case scenario: McCutchen and Longoria have down years, and the pitching can’t overcome the lack of offense.

Hot prospect: Will 24-year-old Steven Duggar impress enough during the spring to set up a platoon situation in center field with Jackson?

Clayton Kershaw and Nolan Arenado have title aspirations. Can Freddy Galvis keep the Padres out of the cellar?

1.ChicagoCubs

Last year: 92-70, first place (lost to Dodgers in NLCS)

Key losses: Jake Arrieta, John Lackey, Wade Davis, Jon Jay, Hector Rondon, Alex Avila

Key newcomers: Yu Darvish, Brandon Morrow, Steve Cishek, Tyler Chatwood

Best-case scenario: Darvish flashes Cy Young form and becomes the ace of a talented staff, Morrow takes the next step to become an elite closer, and Javy Baez and Kyle Schwarber have breakout seasons.

Worst-case scenario: The unofficial swap of Arrieta for Darvish backfires, and the Cubs’ young core takes a step back. Hot prospect: Right-hander Jen-Ho Tseng made two big league appearances last season. He could fill a role out of the bullpen or in the rotation if needed.
