Which makes sense, as it doesn't do them any good to publicly talk about which players they're hoping to trade or exactly how much they have to spend to reshape a roster that missed the playoffs for the first time in a half-decade.
But one thing is certain: The bullpen ranks very high on the Cubs priority list this winter.
At MLB's GM Meetings last week, Theo Epstein acknowledged the bullpen is a major focus for his front office and said, "we need to hit on a number of relievers this winter."
If the season started today, the Cubs bullpen might look something like this:
That also doesn't take into account the potential of Chatwood, Mills or Alzolay getting a shot at the starting rotation (plus Colin Rea, who was added to the 40-man roster earlier this month).
There's not a whole lot of MLB experience in that projected bullpen beyond the closer. Kimbrel has 565 career big-league appearances under his belt, but the other eight names on that list have combined for only 329 relief appearances spanning 374.2 innings.
That's not to say there's no promise in this group - Wick, Ryan and Wieck all impressed in varying degrees of sample size in 2019 while Mills and Chatwood also performed admirably in swingman roles - but there's simply not much of a track record.
To some degree, the Cubs are going to be counting on guys from the aforementioned group (plus other internal candidates like James Norwood and Dillon Maples) in 2020, but there's also clearly a lot of work to do for a unit that struggled mightily in high-leverage spots last season.
"That's a puzzle we're going to be putting together all winter," Jed Hoyer said. "We'll look at every possible angle to do it - minor-league free agency, major-league free agency, trades. We're gonna be creative in how we put a bullpen together, but right now, there's a lot of flexibility.
"It's hard to picture that painting right now, but I think we'll be creative and try to put together a good bullpen."
As Hoyer indicated, there is no one way to put together a quality relief corps.
For example, the Cubs signed Kimbrel to $43 million deal, acquired Wick and Mills in under-the-radar minor-league trades, moved Chatwood from the rotation to the bullpen, drafted Underwood and picked up former second-overall pick (2011) Hultzen on a minor-league deal as he made his way back from a laundry list of injuries. Wieck is the most recent acquisition, quietly coming over from the Padres in exchange for Carl Edwards Jr. while everybody was focused on the Nicholas Castellanos deal.
One such unconventional option could be Brandon Morrow, the oft-injured former closer who initially signed with the Cubs prior to the 2018 season, but was only able to pitch for a few months before missing the last year-and-a-half with ongoing arm issues. The Cubs declined his $12 million 2020 earlier this month and thus owe him a $3 million buyout.
Morrow, 35, is reportedly healthy and has expressed interest in making a comeback. If he doesn't manage to land a big-league deal (which is unlikely given his recent elbow issue and track record of injuries), he is open to signing a minor-league deal with the Cubs, as first reported by the Chicago Sun-Times' Gordon Wittenmyer.
The Cubs would be interested in that, as well, as it's a low-risk, high-upside move. When he's been able to get on a mound over the last four seasons, Morrow is 7-0 with a 1.79 ERA, 1.05 WHIP, 24 saves and 12 holds.
"When healthy, he can certainly be a big part of the solution," Epstein said. "We appreciate his sentiments about if he's gonna sign a minor-league deal, he feels a responsibility that it should be here. That certainly seems like the type of thing that makes sense for both sides down the road."
The Cubs are already probably going to have to get creative to fit all their desired moves into the 2020 budget, so a reunion with Morrow makes sense as a potential piece of the bullpen puzzle. But obviously the Cubs cannot go into the season expecting Morrow to stay healthy all season or relying on him as a key cog.
The biggest key to the success of the 2020 bullpen will be Kimbrel, who had a very forgettable debut season in Chicago.
Kimbrel went 0-4, posted a 6.53 ERA, gave up 9 homers in 20.2 innings and blew 3 saves in 16 chances with the Cubs after signing midseason. He also missed roughly a month of action between a knee injury and then an elbow injury that lingered into September.
Will a typical offseason and spring training be enough to get the 31-year-old back to his Hall of Fame-caliber form?
"Some of the injuries may well have been because of the lack of spring training, ramping up too quickly," Hoyer said. "Of course there's a lot of variables. I don't think we know exactly why he struggled. I thought there were some moments where he looked like he was about to take off and he looked really good and some injuries held him back.
"Hopefully a really good spring training and he can get back on track, really stabilize our bullpen and allow us to build a bullpen without having to worry about the last three outs."
Regardless of how the Cubs build the bullpen this winter, all eyes will be on Kimbrel. If he can't regain his form, it's going to make life a lot more difficult on Epstein's front office and new manager David Ross.
However, it does help that Wick, Wieck and Ryan got valuable experience pitching in high-leverage moments in the midst of a pennant race last season. All three figure to be big parts of that bullpen puzzle moving forward.
Before a minor shoulder issue cut his season short, Chatwood was dialing it up to 99 mph out of the bullpen and impressing in short spurts or in a long relief role. After a long road, Hultzen finally made his MLB debut in 2019 while Underwood struck out all six batters he faced in his season debut in August and showed some promise.
If the Cubs are going to have to lean heavily on the group of relievers without much track record, at least they got a bit of a head start.
"Yeah, it gives us some comfort," Hoyer said. "We have a lot of uncertainty, a lot of moving parts in the bullpen. But the way some of those guys pitched at the end of the year does give us hope that we can find some diamonds in the rough and some of those guys that we found last year can continue to make strides and help us."
