I would think keeping Kimbrel and Ross is a given next year and possibly Kelly if he shows marked improvement from earlier this year. With Ziegler a FA and turning 38 should we try to resign him? Uehara is approaching 42 and probably not up to the rigors of another season. Abad has good stuff if he could be brought out of the funk. I question trying to do something with Tazawa, Barnes and Buccholz. Of our need for 7 RP's next year I only count 4 with a strong chance of helping us. Kimrel, Ross, Abad and Kelly. That means DD needs to add a few from internal sources or through trades. Internally we have Smith, Workman and Hembree who may fill some of our void. Lots to think about in the off season.
Nothing against all these guys, but I really have no strong desire to bring back Uehara, Ziegler, Tazawa or Buchholz.
I think we can do better, go younger and more dependable (healthier history).
