After a flurry of off-season moves, the Boston Celtics are looking drastically different from the one that started the 2024-25 NBA season. Brad Stevens is overseeing a retooling process in Boston, and that means taking chances on players who have struggled to cement themselves in an NBA rotation in recent years.

Parish is the most prolific shot blocker in Celtics history with 1,703, so it stands to reason that he leads the single-season list as well. He made the Celtics look smart for making a big offseason move to trade for Parish as he turned in what would be the best shot-blocking season in franchise history.
