Giannis Antetokounmpo was criticized after Game 5 of Milwaukee’s Eastern Conference series against Boston for not doing more, particularly on the offensive end.

The harshest critic: Antetokounmpo, himself.

He took only 10 field-goal attempts, his third-lowest total of the entire season. Antetokounmpo still had a brilliant stat line, finishing only one assist shy of a triple-double, but the Bucks lost 92-87 and now go back to Milwaukee trailing the first-round matchup 3-2.

Game 6 of the Celtics-Bucks series is the lone matchup on the Thursday night NBA schedule.

“Game 6, I’ve got to come out and be more aggressive,” Antetokounmpo said. “It’s on me. I had open shots, but they weren’t my shots so I didn’t feel comfortable taking them. … I’ve got to be more aggressive, make more plays because definitely, my teammates need me.”

It’s not like he was choosing to not be involved.

The Celtics got Marcus Smart back for Game 5, and Boston is much better defensively when he’s on the floor. Open looks seem to happen far more infrequently when Smart is out there, and the Bucks must solve that riddle or else their season is about to end.

Smart wasn’t the only defensive hero for Boston in Game 5. The Celtics put Semi Ojeleye on Antetokounmpko, and it worked as well as Boston could have hoped.

“Giannis is a heck of a player,” Celtics Coach Brad Stevens said. “You’re not going to be perfect against him. You’re not going to hold him down by any means. He makes plays for other people, he’s very unselfish … but we just felt like we needed a little bit more ball pressure overall, and so that was the decision to go smaller.”

If Antetokounmpko doesn’t come up bigger Thursday, it’ll be Boston going to the second round.

Jaylen Brown is having the time of his young career. In this series, the Celtics’ guard has averaged 23.8 points and 5.3 rebounds. In Tuesday’s win he hit for 14 points.

“We talk so much about staying in the moment and trying to do your role well in that moment that it just becomes another time at the office,” said Stevens. “Everything is heightened once you get in the playoffs, but if you get too focused on that it can be a distraction. But he’s great at what he needs to do, really committed to improving. That mindset has served him well during his tenure here. We’re really encouraged by how he played the other day. He kept us in the game when nothing else was going well. Made huge plays late, and gave us a chance to win.”
