Why The 76ers Could Cover The Spread

The 76ers had a golden opportunity to win Game 6 at home. Unfortunately, they could not get the job done. There is one corresponding factor in all their victories and losses that may determine how this game goes.

Harden had 45 points on 17 for 30 shooting in Game 1. Likewise, he had 42 points on 16 for 23 shooting in the Game 4 victory. Harden also made 4 of 8 shots for 17 points in a Game 5 win. Conversely, Harden shot 2 for 14, 3 for 14, and 4 for 16 in losses in Game 2, Game 3, and Game 6. It should tell you that Harden is the primary factor in whether the Sixers can win this game. Yes, Embiid and Maxey are still around. But Embiid and Maxey played relatively well in Game 6, but it was not enough to take down the Celtics. Ultimately, the Sixers need Harden to shoot the ball well. Harden must take better shots and find a way to get hot.

The 76ers will cover the spread if Harden can take charge and start scoring. Then, the Sixers need Embiid and Maxey to continue to excel. The bench must score more than 11 points.

Why The Celtics Could Cover The Spread

The Celtics are an enigma. Curiously, they struggled in Game 5 and could have found themselves eliminated in Game 6 had they not hunkered down and played tough defense in the fourth quarter.

Tatum performed well in the fourth quarter but struggled throughout. Ultimately, he must play better throughout the game to prevent the Celtics from falling behind early. The Celtics also need Smart to continue to excel in this game. Likewise, Boston needs Brown to keep playing well. The Celtics only played seven players in Game 6. Will that play a factor in this one?

Malcolm Brogdon is the primary guy off the bench. Therefore, expect him to pick up a heavy load while playing in the second quarter. Brogdon played well in Game 6 and must excel in the final game.

But the Celtics also turned the ball over too many times. Thus, they cannot repeat this if they hope to win Game 7. The Celtics must find ways to avoid mishandling the ball and play a cleaner style.

The Celtics will cover the spread if Tatum, Brown, and Smart can thrive. Then, the Celtics must play a clean game and not turn the ball over.
