Pacers-Celtic Same Game Parlay Options

This one should only end one way, how the Pacers and Celtics have both been playing. Indiana is awful, there’s no sugarcoating it. They are firmly at the bottom of the East and are even worse than the struggling Washington Wizards. At the other end of the conference, the Celtics are exceeding expectations and are proving to be one of the more consistent teams, led by Jalen Brown and Derrick White. We think the Celtics will take this one easily, and we expect big games from Brown for Boston, and Siakam for Indiana. You should also expect to see the following same game parlay social picks at Fliff:

Jalen Brown to score over 27 points.
Derrick White over/under on 3pters made.
Pascal Siakam over/under on points.
Andrew Nembhard over/under on assists.
Payton Pritchard over/under on 3pters made.
