CB
Chaim Bloom
★ activeAn efficiency-minded executive from the Rays who ran the Boston Red Sox through a payroll reset and farm-system rebuild, later hired to lead the St. Louis Cardinals.
Across the full 5-season sample, the measured profile stands out most for future-foundation returns (78th percentile). The clearest contrast is cost per win (10th percentile): the measured clubs have paid more per unit of positive WAR than most peers.
5 seasons with salary-era data across 2 stints. All figures are franchise-level outcomes during the tenure, not solely attributable to one executive.
0 pennants · 1 playoff appearance · 340–344 (0.497)

Trade-side columns: RFA is playoff-readiness percentage points added to the future roster foundation. It grades the franchise's entire side of a trade, so the same score repeats for every player acquired in that package. PPA/CPA remain player-level arrival-year probability points.
WAB = wins above what the team's payroll predicted (resource-controlled). WAR surplus = era-neutral value (WAR minus payroll in win-equivalents). Roster surplus $M = dollar value of WAR over cost. Build channels (realized fWAR): HG = home-grown via amateur draft / international signing; Trade = acquired minus surrendered (incl. purchases/waivers); FA = signed minus walked; R5 = Rule-5 / minor-league-draft pickups. Credit follows the acquisition year — home-grown to the regime at the player's draft/signing (not whoever was in the chair when he peaked), trade/FA/R5 to the GM who made the move. Players acquired as prospects before debuting (e.g. Smoltz, Bagwell; Rule-5 picks like Uggla) are counted as trade/R5, not home-grown. All are franchise-level outcomes during the stint, not solely attributable to one executive.
