I'll miss Stearns' influence, and I still believe on the whole that he was very good at making calculated and smart baseball personnel decisions.
What I would like to see from Matt Arnold is a bit more aggressiveness. I know the current front office doesn't prescribe to the "window theory", but I think it's okay to acknowledge that for a small market team creating some greater ebbs and flows from year-to-year with the talent on the roster might not be a terrible approach. I'm not saying I need him to become Dave Dombrowski overnight, but ultimately baseball is an entertainment business and their current product could stand to generate a little more excitement. Since the Brewers are rarely going to be in a position to build a ticket selling type roster through free agency, I think it's okay to pick times where you go a little more "all-in" towards one of two directions. Either (1) trade some assets from the farm to strengthen the lineup in the short-term, especially when you're lucky enough to have the type of home grown pitching talent that rarely comes into place all at once, OR (2) use some of your top current MLB assets (i.e. starting pitching) to take a slight step back in the short-term with the goal of having a stronger roster in the (not-so-distant) future.
Maybe it's partly due to how this year's team played from Memorial Day on, but I'll be really disappointed if they just sort of float along the same path as the past couple of off-seasons.
