Mains: The under-the-radar team adjustments

From SABR member Rob Mains at Baseball Prospectus on May 30, 2016:

Last week, Matt Trueblood wrote about the biggest changes to team Playoff Odds since the start of the season. The five teams with the widest swings: The White Sox, Red Sox, Astros, Mariners, and Yankees. You can guess why. Three of them have been surprisingly good, and two of them have been surprisingly bad. Those teamwide surprises have been underpinned by individual surprises, like Jackie Bradley Jr. (good) and Dallas Keuchel (not). Surprises all, but well-known surprises. If Donald Rumsfeld were writing for BP, he might call them known knowns. (He might call them that anyway. Or he might be too focused on getting you to play solitaire on your smartphone to care.)

I’m looking for unknown knowns. These are teams that’ve changed in less obvious ways—i.e., not the ones you see when you peruse the standings each day—but are nonetheless interesting. I looked for sharp changes from 2015 compared to the 2016 season to date that have probably eluded headlines and highlight shows.

Of course, there are two ways a team can change. They can import a bunch of new players with new characteristics, or their existing personnel can change. I found a little of both in this list.
