This is Part VI of our series ranking the best team units. Today we focus on the best defenses, according to club evaluators -- and out of all the various units we've ranked, picking the best defensive group proved the most difficult.
The Kansas City Royals have played in the World Series the past two years in no small part because of how exceptional they are on defense, and they are an example of the way the entire sport is trending. This winter, teams are spending more on defense (hello, Jason Heyward) and veering away from sluggers who are defensively challenged (like Chris Carter and Pedro Alvarez), and the Royals are the best current example of the idea that success can come through fielding a bunch of guys who make plays on defense.
