Games played by players not qualified for the batting title matter too. If you set a 200 PA minimum, Dozier falls to 16th out of 37 in wRC+, and within 10% of 23rd. http://www.fangraphs.com/leaders.aspx?pos=2b&stats=bat&lg=all&qual=200&type=c,4,6,11,21,-1,34,35,40,41,-1,23,37,38,39,50,61,-1,111,-1,203,199,58&season=2017&month=0&season1=2017&ind=0&team=0&rost=0&age=0&filter=&players=0&sort=16,d The larger point seems to be, Dozier doesn't represent enough of an upgrade for enough teams to be a valuable asset in trade right now. Whether he ranks 12th or top half doesn't really matter.
