I'll speak up here as one of the prominent advocates for making McNeil the centerpiece of the deal. One of the reasons I like McNeil is the fact that he has racked up pretty good numbers in Citi Field, a park that has been even more friendly to pitchers than Marlins Park. If he simply continues those numbers, he is a huge asset to the Brewers. He locks down third base. Given the park factors involved (and I have posted the comparisons before), I think it is very possible for McNeil's offense to take a level up, just as Christian Yelich's did when he arrived. He's cheap for at least one more year, possibly two. He has five years of control. He can play third base, and he already posts very good offensive numbers. In the NL Central, he's an upgrade at third over Moose. He makes Healy the backup at 1B and 3B. The Brewers could do much worse than McNeil. "Could do much worse than X" is not exactly the best selling point when considering whether to trade your elite, cost controlled pitcher.
