DeMar DeRozan hasn't faired well @ Boston, and with Shaq getting more playing time expect this total to hit around 193. Bargnani has played well since returning but he's overdue for a letdown and against the Celtic's D won't be suprised if he's limited to around 20-23 points.
New Jersey Nets/Washington Wizards Under 190
The Wizards are allowing 95.1 points per game at home and New Jersey is awful at shooting. Expect this to hit around 183.
