***From Baseball Reference- Dozier 2013 WAR 3.8 + 2014 WAR 5.2 = 9.0 WAR not 8.9 WAR. That's a 1.4 WAR difference, and the trend appears to be heading in Dozier's direction. If 1.0 WAR is supposed to represent $6M, and now likely $7M, the trend seems to be Dozier's friend for a bigger arb award in 2017, especially being two years younger. Dozier only played half the season in his first (failed) year, and as I acknowledged previously, Walker has the longer track record upon which to judge. And Walker has only played in 129, 133 and 137 games the last 3 seasons, by contrast, Dozier has played in 147 and 156 games the last two seasons, so normalization of WAR isn't entirely accurate in terms of a batting-order-manager-decision difference. In point of fact, Dozier has played 33 more games than Walker over the last two seasons, 5th most for all 2nd baseman,, definitely a valuable data-point for clubs seeking durability at a key defensive position. Another big difference is the area you have completely left out- the Baseball Reference defensive metric in the overall component, which shows Dozier grading out the better 2nd baseman.
