Honestly, Moonslav, our bullpen looks better to me than it did AT THE START of 2016.
Kimbrel is not the world's best closer, but he ought to be more than adequate, and there's something to be said for stability in the closer's role.
Moreover, going into 2016 we thought our setup man was Tazawa, and actually got lucky that an aging Uehara held that role together as long as he did. Going into it this year we aren't trusting to luck nearly as much, Thornberg is a very solid Plan A, and any of Barnes, Ross, or Smith could step into the role, or at least hold onto it for awhile while we sort through our options in trade. That's a hell of a lot better than a burnt-out Tazawa and a Koji held together with spit and bailing wire. Also other options such as Barnes, Ross, and Hembree, are much better-known quantities this year than they were at this time last year.
Going into the year we have some good power arms to look at for middle and late innings, including any or all of Barnes, Ross, Hembree, and Kelly out the gate, and Smith down the road. That's a damn good place to start assembling a 7 man pen and I'd be willing to bet at least 18 teams in baseball are jealous of our depth of options. And that's of course figuring without whatever the 6th starter does in a bullpen role.
Starting the year this is what we look like:
Kimbrel
Thornburg
Ross
Hembree
Barnes
Kelly
(probably Pomeranz)
If you look at the CV's on these guys, any of the 7 could deliver sub-4 relief in any given year, and many of them are good for sub-3 more often than not. Kelly's a wild card, but Kelly is going to be a work in progress and probably near the bottom of the depth chart in the pen anyway. We HOPE for good things from Kelly, but we are not actually in a situation where we have to DEPEND on good things from Kelly -- which from the standpoint of an experiment like this is exactly where you want to be.
Now that said I fully expect the team to need to add to the pen from time to time. Injuries happen, roles shift around, underperformance is a thing that can affect anyone at any time. But guess what? We can add to the pen without spending assets, because waiting in the wings to finish his recovery from elbow surgery is Carson Smith, and even better, we don't have to throw him right into regular bullpen duty if we feel he isn't ready, because we ought to have 7 options ahead of him in theory, all of which are good enough that even if they struggle at first they're worth working with rather than making a panic move.
Are there a few bullpens that are better at the top than ours is? Oh yes. Closer is one of the closest things we have to a weakness in the pen on paper, since Kimbrel had a down year. Is there a bullpen I'd take over Boston's 1-7? Maaaaaaaybe Cleveland, and that's mostly because of Miller. Maybe the Cubs, although not so much post-Chapman. Not too many others
If our bullpen is the closest thing we have to a genuine concern or weakness, this is going to be one hell of a baseball season.
