It's understandable for a team to maximize their chances at winning, but there are ways to go too far.
You don’t have to read the words after this next sentence if you don’t want to: All you need to know is that if the Giants trade for Aroldis Chapman, they’ll have ceded the moral high ground to the Dodgers. That seems like a great reason not to do anything.
But the Giants need bullpen help, and they’d sure love to get a super-premium arm to avoid replacing an average reliever with an average reliever. Chapman is going to be a free agent and the Yankees probably aren’t going keep up in the postseason chase.
