Hypothetical, would you trade Maybin to get Kimbrel back? As much as we need BP help Maybin is too important to the offense imo. Without him it's Cunningham out there every day and that would he brutal.
Given the salary differences, probably not.
There's no doubting Kimbrel's talent, even with his recent struggles. However, it's simply much easier to replace his production (IPs and Saves) with other options than it would be to replace Maybin right now. Those options may not be as flashy as Craig mind you, but we already have serviceable guys in Grilli and Johnson, several in-house candidates being groomed, and names like Holland, Clippard, and Kelvin Herrera (plus others) will be available by 2017 if they're not extended.
Maybin's just a perfect fit right now - relatively inexpensive, and no long-term commitment to get in the way IF the organization decides to go with Peraza or Mallex Smith in CF IF they work out by 2017. IMO, trading Cam right now would be lunacy - he looks like the player everyone expected him to turn into (all credit to his hard work and Seitzer's guidance), he's only owed $8 million in 2016 (making him extremely tradeable as a rental then), and if Hart & Company decides to go another way in 2017 they pay him $1 million and say "thank you".
I've always been a fan of Dexter Fowler like many others here but chasing him in free-agency this winter will require a 4-5 year/$48-$65 million minimum commitment, and put him directly in the way of several other promising prospects.
