Bruins Will Not Renew Assistant Coach Jay Leach’s Contract

Reportedly, Boston will search for a new defensive coach to address persistently weak defensive metrics.

Overview

  • The Bruins will not renew Jay Leach’s contract, a development first reported Thursday by David Pagnotta of The Fourth Period.
  • Leach spent two seasons running Boston’s defense and taking on an expanded penalty-kill role before the club’s first-round playoff exit this spring.
  • Under Leach the team posted poor defensive numbers, including 3.01 goals allowed per game (14th in the NHL), an expected goals against per 60 of 3.57 (tied second-to-last), 30th in high-danger chances allowed per 60 at 13.52, and consecutive 24th-place penalty-kill finishes (76.3% in 2024–25 and 77.0% in 2025–26).
  • Leach is expected to be available to other clubs and has been floated as a head-coaching candidate by league reporters, increasing his chances of landing elsewhere this offseason.
  • Boston has begun searching for a replacement, with defensive specialists such as Chris Hajt mentioned, and the move is part of an early offseason staff reshuffle aimed at fixing the team’s underlying defensive issues.
