The most unpredictable players of 2017
What's worse than a player who underperforms or fails to meet expectations? One who can be great one day and horrid the next.
As we move closer to the start of spring training, here is each MLB team's biggest question mark.
Since 2000, there have been 30 players who have posted at least 8.5 WAR in a season, not counting Mike Trout and Mookie Betts from 2016. Of those 30 players, here are the five biggest drop-offs the following season:
Barry Bonds, 2004 to 2005: -10.0
Bryce Harper, 2015 to 2016: -8.3
Scott Rolen, 2004 to 2005: -7.5
Adrian Beltre, 2004 to 2005: -6.3
