Nice article by ESPN's Doolittle:

"They are younger. They are more athletic. They are more fun. They are deeper. And because of all these factors, they are better."
"Through the Boston series, no team had more WAR from rookies than Milwaukee."
"Of the nine players who have currently played the most at their respective positions, only three are carryovers from last season: Tellez, Adames and Christian Yelish."
"...players so often seem to just get better after they join the Brewers. For all the attention that has gone to teams like the Rays, Dodgers and San Franciso Giants for their ability in this area, Milwaukee ranks right with them. Two of the offseason acquisitions, Anderson and Contreras, are the latest examples of this."
"The Brewers rank in the top 10 positionally by fWAR at most spots and are in the positive at most of the others, except for DH. And that ranking could change fast if Winker gets going. They rank second in Fangraphs' team defensive metric and have an elite ERA+ of 120.
In other words, this is a complete team without any glaring weaknesses and with excellent depth (as long as the injury bug doesn't get worse), a balanced set of skills and a number of players who should continue to trend in a positive direction."
