Why the Celtics will win Game 1

The collective experience, the best starting five in the league, the No. 1 offense led by Jaylen Brown and Jayson Tatum, and the No. 2 defense led by Jrue Holiday and Derrick White will be the difference for Boston in Game 1.

Why the Mavericks will win Game 1

Luka Doncic and Kyrie Irving are on a roll offensively, and the Mavs' execution against three 50-win opponents in the West playoffs has prepared them for this moment. And they are a team that is 7-2 on the road in this year's playoffs.
