Bill Stoneman

Born Apr 7, 1944 · Oak Park, IL · age 82

Built the Anaheim Angels' 2002 World Series champion — the franchise's first title — through a balanced, homegrown-and-bullpen approach.

10 seasons with salary-era data across 3 stints. All figures are franchise-level outcomes during the tenure, not solely attributable to one executive.

Roster value distribution — career average — depth vs. stars

Every roster slot ranked best→worst by WAR, averaged across Bill Stoneman's seasons. Bars = his rosters; the black line = the league-average player at each slot. Staying above the line deep into the roster is the depth edge.

Players acquired — 165 players, by realized fWAR for the franchise (scroll for more)

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.
