Now that spring training is mercifully almost here, we complete our team-by-team tour of big-picture observations of the majors. Today's tier consists of the top 10 clubs in baseball, ordered from worst to first by my current forecasted run differentials. The analyses for this group will have a different tone than the ones you read in the previous installments. The bottom-tier edition tended to be an evaluation of each team's long-term prospectus. The middle-tier edition questioned the direction each team is headed. But for this group, the focus is more on the short term, with extra attention paid to the coming 2017 season.
