Dozier is a significantly better than average MLB 2nd baseman. Baseball is a game of streaks - any small sample size you choose (1/2 a season, for instance) will undoubtedly be better or worse than any other you choose, but the body of work is terrific this year. For qualified 2B this year, he's 7th in OPS & 5th in WAR. While any stat's imperfect, you don't trade away one of the few above-average major leaguers on the team--while he's young--in hopes that we someday find another one.
