Marshall knows Indiana forward Pascal Siakam will need to continue to step up with Tyrese Haliburton (hamstring) questionable. He averages 21.7 points and 7.7 rebounds per game in the 2024 NBA playoffs. In his last outing, Siakam had 28 points and five boards.

He is also aware Boston guard Jaylen Brown is a smooth two-way threat. Brown has great length and athleticism to be effective on both ends of the floor. He logs 24.8 points and 6.5 rebounds per contest in the postseason. In his last game, Brown dropped 40 points and five rebounds.
