Miami is confident it will be able to compete in 2015 after adding several pieces this offseason in addition to extending Giancarlo Stanton. The Marlins are still looking to add a fourth outfielder, but SB Nation's Grant Brisbee notes that the club does not have any major holes when compared to other major league teams.
Although it is the midpoint of the offseason, the Marlins likely took care of all notable moves during and shortly after the Winter Meetings. After signing Stanton long term, which was the organization's primary offseason goal, the Marlins promptly added Dee Gordon, Michael Morse, Mat Latos, Martin Prado, and David Phelps to their roster. Miami did lose top pitching prospect Andrew Heaney, but still has a number of starting pitchers that will be looked at this spring.
Ultimately, the perception that the Marlins do not need to make any large additions is the result of the club addressing its primary needs. Following the Stanton extension, the team was seeking a veteran starting pitcher and key power bat. Miami added both by acquiring Latos and signing Morse, respectively. The Marlins were not looking to add a second baseman this offseason, though Gordon adds speed to the top of the lineup and should prove to be an upgrade. Moving Casey McGehee was not reportedly planned, either, but the Marlins felt Prado will be an upgrade.
As a whole, the Marlins' roster seems comparatively complete. There will likely be competitions for bench roles and a pair of bullpen spots, but the lineup and rotation appear to be settled. Despite the fact that the Marlins may be in a good position, as Brisbee notes, it is easy to "pick apart the lineup and rotation." Latos, Henderson Alvarez, and Jarred Cosart are expected to break camp as the first three members of the rotation, but beyond that a competition may be necessary (assuming Dan Haren retires). Tom Koehler, Aaron Crow, Brad Hand, David Phelps, and Justin Nicolino will all likely be considered for the final two slots. In the context of the lineup, Morse will likely hit behind Stanton, but Jarrod Saltalamacchia, Adeiny Hechavarria, and Martin Prado may see time in different spots throughout the order.
In addition to seeking a fourth outfielder, the Marlins may be in pursuit of a left-handed pinch hitter, although Justin Bour could be given the job. The club could also consider possibilities to complement Mike Dunn as an additional left-hander in the bullpen, with Rule 5 draft pick Andrew McKirahan expected to be looked at.
Miami, seeking consistency, may indeed be in a solid position when compared to other clubs. There are no clear holes, but the Marlins could look to upgrade several positions when spring training gets underway.
