I think the Trade Value webesite is pretty neat, and it does a nice job of generating fan site discussion and hot stove fodder, but I'm not sure it always does a great job of actually valuing players properly, or really let's you mish mash players contextually. A player might be worth X, and another player might be worth Y, but if you just take a pile of players worth XYZ, are they lumped together worth XYZ? I'm not sure that's the case. There's a lot of factors that I don't think a website calculator can take into account. The sum of a pile isn't always worth the whole. EDIT TO ADD: I want no part of Trevor Story and the money he's owed outside of Coors, if it involves giving up Huira . I don't like the argument of "Lemahieu hit good in Yankee stadium, so Story will probably/possibly/maybe be fine". 1) Yankee stadium might be as good a hitters park as COors. 2) one guy hit great outside of Coors, and anyone can probably quickly find 10 guys that struggled once they were no longer Rockies. IF they stay with a juiced ball, he will be fine! Welll...... they had a juiced ball this year and he didn't crack an .800 OPS outside of Denver. Is that a gamble the Brewers should take with a cornerstone bat like Keston Huira? I'm not sure about that. EDIT 2 to add, If the calculator requires the Brewers to take a busted contract like Wade Davis to make it "work", it's fundamentally broken. The Brewers aren't in position to be paying 8.00 ERA relievers 15 million dollars per year to make trades work to get expensive Shortstops, in place of their currently inexpensive .950 OPS 2nd baseman.
