At first glance, it's easy to see why - they're in the playoffs for the first time as something of an underdog and "surprise" team - but that's not the recent Cubs squad we should be comparing the 2018 Brewers to.
This Milwaukee team is a lot more like the 2016 Cubs.
1. They're not a surprise.
Nobody expected the 2015 Cubs to win 97 games and wind up in the NLCS. They were expected to compete very soon, but everything went right in a red-hot August, they rode Jake Arrieta's right arm to the NLDS and then toppled the Cardinals to get to the LCS, where they ran into the brick wall that was Matt Harvey and and the Mets pitching staff.
The 2018 Brewers are not - and should not be - a surprise. Anybody who was caught off guard by this team being so good hasn't been paying much attention. The Brewers were leading the NL Central in 2017 for much of the year before a late-season fade that coincided with the Cubs' late-season surge.
This Milwaukee squad was always supposed to be one of the top teams in the NL in 2018 and they really hit their groove in September to chase down the Cubs. Still, it took a Game 163 to force a changing of the guard atop the division.
2. They greatly improved expectations with a big free-agent OF signing over the winter.
Cain has provided quite a bit more offense in the first season of his 5-year, $80 million contract but both Cain and Heyward provided leadership in the clubhouse and elite defense in the outfield in the first years with their new teams.
3. The Brewers have the NL MVP.
This one's an easy comparison to make, though Cubs fans will hate it.
Christian Yelich is this season's NL MVP. Sorry, Javy Baez fans. "El Mago" had a great season, but it's impossible to give the award to anybody but Yelich.
Yelich winning the league's most coveted accolade would be another perfect tie-in to the 2016 Cubs, who had Kris Bryant take home NL MVP.
4. They have a dominant LHP out of the bullpen.
Josh Hader has been doing his best Aroldis Chapman impression in 2018 as an absolutely dominant southpaw out of the bullpen. Unlike Chapman, Hader's spent all season with the Brewers, but like Chapman in '16, Hader will be leaned on heavily for multiple innings throughout the rest of the playoffs.
5. They picked up some valuable in-season assets.
The 2016 Cubs dealt for Chapman, but they also traded for reliever Joe Smith and called up Willson Contreras in the middle of the year, who provided a spark for the offense.
The 2018 Brewers have acquired plenty of valuable assets along the way this season from Mike Moustakas to Jonathan Schoop to Erik Kratz (more on him later) to Gio Gonzalez. But one of their most important additions (especially in October) was the promotion of top prospect Corbin Burnes, a flame-throwing right-hander who posted a 2.61 ERA in 30 regular-season games and allowed only 1 hit in 4 shutout innings in the DS.
6. They're on a mission with a chip on their shoulder.
The 2015 Cubs had a little bit of a chip on their shoulder as they attempted to take down the divisional powerhouse that was the St. Louis Cardinals. But again, they were a surprise contender - even within that clubhouse (especially early in 2015). But after falling short in the NLCS, the Cubs retooled over the winter and came back with one goal in mind - to win the World Series.
It was a goal they accomplished. We'll see if the Brewers will be able to do the same, but they certainly came to play in 2018 with a chip on their shoulder and the ultimate goal of winning the final MLB game of the year.
The Brewers didn't lead the division from Day 1 and weren't able to coast into October, but they still wound up with homefield advantage throughout the NL playoffs.
7. They have journeyman catcher who is winning over fans' hearts.
This is a fun one.
The 2016 Cubs had David "Grandpa" Rossy who still elicts deafening cheers whenever he's shown on the giant video board at Wrigley Field. The 2018 Brewers have Kratz, who has become a fan favorite recently and was mic'd up for the final out of the NLDS.
Ross was 39 when he helped lead the Cubs to the 2016 World Series and Chicago was his eighth stop (seventh different team) along his MLB journey. Kratz is 38 and on his ninth stop (seventh different team) along his MLB journey.
In fact, Ross and Kratz are so intertwined, they've already been compared to each other by MLB.com.
But the major difference is Kratz has zero postseason playing experience until a week ago. Will he be able to ride off into the sunset with a championship ring on his finger the way Ross did?
We'll have an answer to that over the next few weeks in the final chapter of the Brewers' 2018 season, though Cubs fans surely wouldn't be too happy to see their division rivals celebrating with a World Series parade just 90 minutes north of Wrigley Field.
