First off, Game 3 was awful. The Raptors’ offense was disjointed throughout, only saved by Kawhi Leonard for stretches (an increasingly concerning trend), and their defense was about as bad.
But a lot of that was just players having really bad games. Some of it was poor tactics and poor preparation — such as coming into the game with a plan to establish Marc Gasol as a scorer because the 76ers had shown a willingness to cover him with Tobias Harris. A good idea, except then they stuck with that plan even as the Sixers put Joel Embiid Gasola, leading to several wasted possessions trying to force offense through an unfavourable matchup.
