Starting caliber players are imminently replaceable. MVP-caliber ones typically are not. Yeah, the Brewers seemingly gave up good value. They got back incredible value. Still, it appears that all 4 of these guys stand a chance of being at least MLB regulars. That is pretty rare in a quantity for quality deal like this. Kudos to the Marlins for identifying four possible/likely future contributors for a guy they needed to deal. Kudos, too, to the Brewers for having a solid and deep enough system to be able to make this deal. Makes both teams look good. Im not taking one side or the other on the trade but to say starting caliber players are replaceable is not true. Just look at some of the well below replacement level crap we've run out there over the years. And superstars mean next to nothing in baseball if there aren't quality players and depth to surround them with.
