In the Boston Celtics' playoff series against the Orlando Magic, identifying a key player aside from Jayson Tatum is crucial. With the Celtics favored to win, they face unique challenges due to the Magic's defensive prowess, characterized by their size and strength. Potential candidates for this pivotal role include Jaylen Brown, Kristaps Porzingis, and Derrick White, each bringing unique skill sets to the floor.

Brown's scoring ability and defensive tenacity will be essential, while Porzingis can exploit mismatches with his height and shooting. Meanwhile, White's playmaking and perimeter defense could tip the balance in crucial moments. The series will present a test of depth for the Celtics, making the contributions of these players even more significant.
