I wonder what is up with Chris Coghlan. He has had above WAR values of 2.4 and 3.3 in 2014 and 2015 respectively with the Cubs, and whenever he gets sent down to AAA he hits well (according to the stats), but now with the Blue Jays he seems like a defensive liability and not reliable at the plate - http://www.fangraphs.com/statss.aspx?playerid=6878&position=OF
Unfortunately, this year Devon Travis is taking a similar route as Chris Coghlan, but hopefully Devon can turn things around. Ryan Goins seems like a similar type of player who can never seem to be a consistently good player although he has shown promise at times (however, Goins has been fairly consistent defensively).
