Why Kendrick Perkins believes the 76ers will upset the Celtics in Game 7

The shooting is certainly a concern for the Celtics heading into Game 7. Not only have they been held under 100 points the last two games, but Boston shot 13-of-50 from deep in Game 2, 11-of-39 in Game 5 and 12-of-41 in Game 6, all of which were double-digit losses. That reliance on the long ball has essentially made the Celtics more one-dimensional with fewer free-throw attempts and much less of a paint presence.

The Celtics have had no answer for Embiid, who went off for 33 points (12-of-23 FG) in Game 5 and was two assists away from a triple-double in Game 6. Maxey has been just as impressive with at least 21 points in each game of the series, including a team-high 30 points (11-of-22 FG) in the Game 6 win for the 76ers.

Even after the 76ers dropped Game 1, 123-91, rookie VJ Edgecombe had a historic performance in Embiid's absence and helped get Philadelphia on the board in the series. 

If the Celtics are going to pull Game 7 out, they must get more from Jaylen Brown, who is only 3-of-10 from deep and 5-of-11 from the charity stripe in his last two games. That is not exactly the most encouraging for a player who has taken on a larger role this season while Jayson Tatum was sidelined with a ruptured right Achilles tendon.

Tatum exited Game 6 with reported calf tightness and was also seen with a wrap on his left leg as well. While he did not seem concerned about his leg, the Celtics will need to monitor him closely to make sure he is ready to go, or at least rested up if they make it to the Eastern Conference semifinals.

This did not look like much of a series when the Celtics held a 3-1 lead. With Game 7 set for Saturday, and the 76ers looking as confident as ever, the Celtics could face a shocking first-round exit if they are not careful.
