The story of Boston’s 60-win season was supposed to be Tatum and Brown. It still mostly is. But the quiet co-story — the one Joe Mazzulla brings up in every press conference and the one opposing coaches keep flagging in scouting reports — is what happens when the starters sit.

Sam Hauser shoots 43% from three. Payton Pritchard is averaging 12 points a night off the bench. Together, on the court without any starters, they have a net rating of +18.2 over 412 minutes this season.

That’s not a role-player number. That’s a “you have a problem” number.
