Making the postseason isn't the only reason to make modest improvements to the team. Most of this team is young and inexperienced. Keeping them focused for an entire season through a division race may be a priority for this front office (along with increased fan interest). This is a 59 win team that imploded just last season. Making a few modest improvements to vault them into 80 win territory (or better) isn't unreasonable, even if you think you only have a moderate chance of making the postseason. Stats, sequencing, and projections are important but (and it pains me to say this), baseball is not played on a stat sheet. Give the team a chance to win this season without breaking open the farm, hope for the best, and then try to build a better team next season with a bunch of young players who expect to win.
