We take a look at Nolan Arenado’s eight-year, $260 million deal with the Colorado Rockies and the recent run of extensions this offseason — including Aaron Hicks and Miles Mikolas (3:42). Then freelance journalist and data consultant Rob Arthur joins the show to talk about how fast analytics are changing in baseball, how accurate our assumptions about players are, and what this might mean in the future for the on-field product and front-office decision-making (37:22).Hosts: Michael Baumann, Ben Lindbergh, Zach KramGuest: Rob Arthur
