Golden State hasn't performed up to expectations as their defense is terrible and they don't have much of a bench. Also not having Wiggins in the lineup is hurting them.
The good news for fans is that Boston is tough and will be looking revenge from the NBA Finals.

The Celtics are shooting the ball more efficiently, ranking second in assist-to-turnover ratio, and, somehow, Tatum is even better than last season and Brown has taken the next step from All-Star to All-NBA-caliber.
Lastly, the Celtics are 7-1 ATS in its last eight games following a straight-up win of more than ten points. Even thought Golden St is 11-2 at home I think Boston is the better overall team and Saturday night winner.
