The Celtics will be looking to avoid back-to-back losses for the first time this year, and they likely come out running as they want to put on a show on Christmas. Tatum was out in their Monday night's 108-104 loss at Orlando, so they will want to bounceback big here. Tatum is 50/50 to go here but we actually like the over as we think Philly will be up for this game as well and be an active dog.
