The general manager for the Milwaukee Bucks and general manager for the Milwaukee Brewers chat about sports management.

Sport as Science

Jon Horst, general manager, Milwaukee Bucks
David Stearns, general manager, Milwaukee Brewers

Milwaukee had a heck of a pro sports year in 2018, and for that we can thank our young tandem of general managers, David Stearns and Jon Horst. Stearns’ overhaul of the Brewers’ roster last winter included trading for eventual MVP Christian Yelich and assembling an unconventional, under-the-radar pitching staff that carried the team to within one game of the World Series. Horst has overseen a coaching change that, along with key roster additions and subtractions, has converted the Bucks from young, talented underperformers to legitimate contenders to reach the NBA Finals – at least through the first quarter of the season.

The two GMs are also friends, and patriarchs of young families. Horst, 35, and his wife have a 5-year-old daughter and 2-year-old son; Stearns, 33, and his wife welcomed baby Nora on the eve of the Brewers’ postseason run. (“I haven’t been getting a lot of sleep,” he says.) Their mid-November conversation began with how sports analytics – once an invisible force shaping the product on the field or court – is becoming increasingly visible to fans.  – Moderated by Chris Drosner

Sport as Science: Jon Horst and David Stearns

DS: In baseball, we’re fortunate that literally everything that has happened on a major-league field has been documented going back 70 to 75 years or so. And when you start with that trove of information, it can lead to a lot of really exciting discoveries. It’s been a progression over the last 20 years, how information, big data and advanced analytics have informed our decision-making process.

JH: From the basketball perspective, it’s probably like a younger, less mature version of that. The shift that’s happened in the last 10 years, or really the last three or four years, is this tracking data and the ability to get deeper information beyond the base box score stats. Here with the Bucks, we’ve really tried to use it to give the coaching staff data and information to help support their style-of-play philosophy, and to try to find value on the margins in roster construction.

RELATED  Conversation on Housing: Kail Decker and Raphael Ramos

DS: Some of those tracking technologies that have infiltrated basketball also have made meaningful impact in baseball over the past decade. We now have Statcast, which is now in the public domain and if you’re watching a major league broadcast, you’re very much aware of some of the metrics that tracking technologies and camera systems and Doppler radars around the ballpark allow us to capture.

JH: My biggest surprise in having the role [of general manager], without a doubt, is the limited amount of time that we actually have to focus on what we’re really held accountable for, which is the talent that we put on the roster. There’s so much of managing staff, putting out fires.

DS: I’ve been fortunate that so far I’ve been a better executive in baseball than I was as a high school or college fantasy baseball manager.

JH: I played fantasy football for about three years and I’m horrible at it. I just delegated it. One of my guys who’s really, really valuable to me at running the Bucks, I just said, “I need you to run my fantasy football team,” and now we’re like 9-1.

DS: I grew up a huge sports fan in New York City and was a huge fan of all four major sports. Now I just spend my time outside baseball focusing on the local teams, but I try to catch Bucks games when they’re on and I’m at home, and most Sundays I’m tuned into the Packers. I think we all have a respect for what our counterparts in other sports are doing, and it’s fun to see the success that the Bucks are having this year.

RELATED  Conversation on Development: Bob Monnat and Melissa Goins

JH: It’s fun for the state and for you and [Packers GM] Brian [Gutekunst] and myself to be similar in age, and similar in opportunity with these state-loved franchises. It’s good for the state to have three competitive, successful sports franchises.

DS: I think there’s a mutual respect, to understand the challenges that even if it’s a different sport, we’re all facing some of the similar challenges. It’s unfortunate that our seasons don’t align particularly well, so the time we actually get to spend together or talk is probably limited by the fact that when I have a little bit of down time, you’re going full force and same thing the other way around.

JH: You and I have had some great conversations about analytics and how they use it, sports psychology and just general structures for scouting staffs. The more that we get to know each other, the more we spend time with each other, I think there’s a lot we can learn from each other.

DS: We text fairly regularly, more to just check in and to let each other know that we’re following what the other guy is doing. That support is definitely helpful.

JH: We were really good friends until about six weeks ago [when Nora was born], now I haven’t heard from you. [Laughs]
