Boston disastrously lost Game 4, allowing James Harden to drain a last-minute 3 to seal a one-point victory.

The Celtics then posted a complete dud in Game 5, but despite five games already being played, there are many questions to answer about both teams.

Can Boston recover from a 3-2 deficit?

Can Joe Mazzulla make the necessary (or any) adjustments?

Can the Celtics shoot remotely better from 3-point range?

Can Harden and Joel Embiid be stopped in the pick-and-roll? 

Here is our prediction and pick for Celtics vs. 76ers Game 6.

Odds courtesy of Caesars, current at the time of writing and subject to change. 

Spread: Celtics -2 (-110) vs. 76ers +2 (-110)

The 76ers ran a pick-and-roll set 33 times in Game 5, accounting for over 40% of their offensive plays, per ShotQuality.

Embiid and Harden ran the same set repeatedly and burned the Celtics. 

Harden finished with 10 assists, primarily by dishing to Embiid, who finished with 33 points and six made field goals coming off the high screen in the mid-range area. 

The Celtics are icing these ball screens, allowing Harden to drive left while Embiid rolls into space.

The C’s have refused to change their coverage schemes in this series, and it’s been a bloodbath. 

More importantly, it’s been a consistent, steady source of offense for the Sixers, something the Celtics have not found. 

Jaylen Brown and Jayson Tatum have been great in spurts, but they’ve also disappeared for large periods. 

For example, Tatum didn’t make a single field goal in the first half of Game 4 and finished with only two points in the first quarter of Game 5.

Brown scored 12 points in the first quarter of Game 4 and didn’t take a single shot over the final 17 minutes, all while the Celtics choked away a late overtime lead. 

The Celtics are at their best when moving the ball and running the floor.

Yet, they continuously haven’t done that, instead opting for 21 half-court isolation possessions in Game 5, with eight finishing in off-the-dribble 3s. 

As a result, the Celtics have been inconsistent.

They can get hot from 3 and steal games, but they’ve been horrendous in the most significant moments of this series. 

Coach Mazzulla doesn’t seem ready for playoff basketball, and I’m not betting he suddenly makes the necessary adjustments six games into the series. 

The public will heavily back the road favorite Celtics, thinking they’ll show up with their backs against the wall.

However, I think this makes them overvalued, and I’m always willing to fade the public.

Additionally, The Action Network App has tracked sharp money coming in on Philadelphia despite most bets being on the other side.

We characterize this as reverse line movement, a profitable bet signal. 

I’m done believing in the Celtics.

Despite their huge talent advantage, coaching and schematics are too important in playoff basketball, and the Celtics look vastly outmatched in both areas. 

I’ll back the Sixers as sharp home dogs in Game 6. Given I think they’ll win the game, I’d play them at a PK or better.

Philadelphia 76ers +2 (-110) | Play to PK (-110) — Caesars
