Celtics vs. Bucks: Boston’s defense faces another test of separation

Boston beat Milwaukee by seven points Wednesday. Now the Celtics return to the same matchup after a 39-point win at Charlotte, while the Bucks are trying to end a five-game losing streak. The temptation is to let those latest results define the rematch. The more useful question is whether Boston can create the kind of separation it didn’t manage against Milwaukee the first time, with its defense again setting the terms.

The first meeting is the starting point

The Celtics won 109-102 in Boston, but Milwaukee covered the spread. DraftKings again lists Boston as a 12.5-point favorite for Sunday’s game, now at Fiserv Forum. That earlier result doesn’t set a ceiling on the Celtics, but it makes the distinction between winning and producing a large margin especially concrete.

Boston is 7-2 outright and 4-5 against the spread this season. Milwaukee is 1-8 outright and 3-6 against the spread. The teams’ records point in the same broad direction, yet Boston’s wins haven’t automatically become covers at the numbers it has been asked to lay.

Our team grades show why the size of the margin is an open question. The Celtics grade A- on defense and D on offense; Milwaukee grades C defensively and C+ offensively. Boston’s clearest strength is making the opponent’s night difficult. That can build a lead without requiring an offensive avalanche, but it still leaves the Celtics needing enough scoring to keep extending it.

Charlotte showed Boston’s ceiling

In the 119-80 win at Charlotte, AP reported that Jayson Tatum had 34 points, nine assists and eight rebounds, while Derrick White scored 18. Boston made 17 of 31 threes in the first half and led by 31 at the break.

That was a glimpse of how quickly Boston can pull away when its shooting catches fire. The rest of its recent scoring has been less explosive. Before Charlotte, Boston had scored 109 against Milwaukee, 93 at Houston and 108 at Orlando. The recent offense has included a rough night as well as the blowout.

The defensive results have been steadier over those four games: opponents scored 97, 109, 102 and 80, in order. Milwaukee has already experienced that problem once, and its own recent scoring offers little spare room. The Bucks have finished with 100, 102 and 107 in their last three games.

Milwaukee needs its response to survive the second half

The Bucks’ 121-107 loss to Toronto came after they led by as many as 15. AP reported that Toronto won the second half 70-47. Tyler Herro finished with 23 points and ten assists, and Brayden Burries had 21 points and 11 rebounds.

Milwaukee needs those contributions to last through Boston’s defensive pressure. An early lead or one productive stretch won’t be enough if the next response disappears.

The total also depends on sustained offense

The total is 221.5. Seven of Boston’s nine games have gone under their posted totals, including the last five. Milwaukee’s last three have also gone under, though five of its nine games this season went over. For the Bucks, the recent unders have come alongside lower scoring of their own, rather than a run of defensive control: they still allowed 121 points to Toronto.

The first meeting produced 211 combined points against a 222.5 total. Sunday’s line is slightly lower. Milwaukee’s latest game, meanwhile, finished under its own 228.5 total but above this one. The historical under labels can hide different scoring outcomes. Boston’s defense and Milwaukee’s ability to keep scoring through it remain the central basketball questions.

Watch whether the Celtics can turn stops into sustained separation, and whether the Bucks can respond after their first good stretch ends.
