The Boston Celtics suddenly have a Joel Embiid problem they failed to finish off

He missed all five of his threes. Philadelphia still won by 16 in Boston. That tells the real story of the night.

Embiid worked from the post, the foul line area, and the middle of the floor. He forced Boston’s centers to absorb contact. He made the Celtics choose between single coverage and late help. He gave the Sixers structure in the exact places their offense needed it.

That is the Embiid version Philadelphia needs in Game 6. The jumper can come and go. The control has to travel.

Philadelphia finally made Boston guard the whole possession

Boston can live with difficult jumpers. It can survive isolated scoring bursts. The Celtics get uncomfortable when Embiid’s touches create decisions for everyone else.

That happened in Game 5. Embiid’s aggression opened the floor, and the Sixers had enough shooting around him to make those possessions matter.

Grimes became the swing piece. His 18 points on 4 for 7 shooting from three gave Philadelphia the spacing release it has been chasing all series. When Boston shaded toward Embiid, Grimes gave the possession a clean ending.

Embiid said after the game that Grimes was huge because his spacing forced Boston to decide whether to double. That is the entire Game 6 problem for the Celtics. Help too much, and Philadelphia has rhythm threes. Stay home, and Embiid gets to attack one-on-one.

The fourth quarter showed the defensive blueprint

The Sixers won the fourth quarter 28 to 11. Boston missed its final 16 shots. The Celtics’ offense lost its spacing rhythm, and Philadelphia deserves credit for that.

Embiid said the defensive emphasis was simple. No threes. Stop overhelping. Make Boston play one-on-one.

That matters because Boston’s best basketball usually comes from creating a math problem. Drive, spray, relocate, punish the late closeout. Philadelphia spent too much of the series giving the Celtics those clean advantages.

Game 5 looked different late. Paul George handled tough defensive work against Jayson Tatum and Jaylen Brown. Maxey and VJ Edgecombe rebounded from the guard spots. Philadelphia stayed attached long enough to make Boston search for answers deeper in the clock.

Maxey gave the Sixers the pace they needed

Maxey finished with 25 points, 10 rebounds, and five assists, and his value went beyond the box score. He kept Boston’s defense stretched vertically and horizontally.

His deep threes forced higher pickups. His drives forced Boston’s guards to defend without relaxing into Embiid coverage. His rebounding helped finish possessions during the fourth-quarter shutdown.

That balance matters because Embiid is still working his way back into rhythm after surgery. He played 39 minutes only 19 days after an appendectomy, and he admitted he had only one core session during recovery.

Philadelphia cannot treat Game 6 like a normal Embiid workload game. It needs Maxey’s speed, Grimes’ shooting, George’s two-way steadiness, and Edgecombe’s energy to keep the burden from becoming too heavy.

Game 6 now has real pressure on Boston

The Celtics still lead the series. They still have more margin because of their shooting, depth, and home-court edge if the series returns to Boston.

Game 5 changed the feel of the matchup because Philadelphia found a repeatable shape. Embiid in the middle. Maxey applying pressure. Grimes spacing the floor. George defending stars. No reckless overhelp that turns into Boston threes.

The Sixers need a lot to go right again. Embiid has to hold up physically. Grimes has to keep making Boston pay. Maxey has to keep touching the paint. Philadelphia’s defense has to stay disciplined for four quarters.

That is a difficult formula. It is also a real one. The Sixers finally made Boston play the kind of game that gives Philadelphia a chance.
