David Schoenfield: Losing No. 1 starter Patrick Corbin for the season is a big blow for the Diamondbacks' playoff hopes, considering the rotation was already viewed as mediocre at best as they were counting on injury-prone Brandon McCarthy and free agent Bronson Arroyo, who had back issues in spring training. That might force the Diamondbacks to feed top prospect Archie Bradley into the rotation, and, although he has one of the best arms in the minors, whether he's ready to throw enough strikes remains an issue. MVP runner-up Paul Goldschmidt and trade acquisition Mark Trumbo could combine to hit 80 home runs, but the lineup is righty-heavy and dependent on catcher Miguel Montero hitting better than he did last year. Trumbo is also a liability defensively in left field, although A.J. Pollock and Gerardo Parra are plus defenders in center and right, respectively. The D-backs look like a team with as wide a range of outcomes as any team. If the rotation stays healthy and performs, they could win 90 games and contend for the playoffs, but you could easily see them morphing into a 90-loss team just as easily.
Christina Kahrl: There's plenty of name recognition and depth in the rotation to survive Patrick Corbin's injury, but to keep up in the NL West they'll need rookie Archie Bradley to break through. The offense starts and ends with Paul Goldschmidt and Mark Trumbo. If the Snakes struggle, you can bet Kirk Gibson's yen for scrappers will need scrapping.
