Justin Hollander

Justin Hollander is the general manager of the Mariners, in his 4th year as the lead executive. FanVerdicts evaluates MLB GMs on the same four-grade framework applied to players and teams: Contract Value Index for the GM's contract portfolio (the deals they signed), Performance for the on-field results of the players they assembled, Sentiment for media and fan perception of recent moves, and Fan Verdict for community voting on the GM's body of work. Current grades for Justin Hollander: Contract Value Index pending, Performance B-, Sentiment C, Fan Verdict pending.

Each GM grade is rolled up from the underlying transactions attributed to that GM's tenure. When a GM signs a player, that signing's Contract Value Index grade flows into the GM's portfolio score; the same player's subsequent performance and sentiment grades flow into the GM's respective summaries. Phased attribution applies for new GMs: the first three years weight the prior GM's legacy deals at 100%/66%/33%, ramping the new GM's ownership of roster outcomes.

For broader context, the MLB hub has team rankings, GM report cards, and the transactions feed. The MLB GM rankings page ranks every front office side-by-side on the same four dimensions.
