Miami is 8-0 at home this season. Going back to last season, the Heat are 9-1-1 ATS in their last 11 home contests. Miami shoots 51.4 percent from the floor at home compared to 45.1 percent away.
The Heat give up 17 fewer points per game than the Wizards. Washington is 12-29-1 ATS the last 42 times it has been on the road facing an above .500 home foe.
Not only is Miam vastly superior to Washington - which this point spread reflects - but it draws the Wizards being in a highly favorable situational spot. The line doesn't fully reflect that. 
Washington is off maybe its best game of the season, a 119-113 home win against the 76ers. The Wizards had lost three in a row prior to that victory. The Heat are off a disappointing, 112-93, road loss to the Celtics from Wednesday. Miami is 18-7-1 ATS following a non-cover. The Heat also are 14-2-1 ATS the past 17 times when going against a below .500 opponent. 
The Wizards are shorthanded in the middle with center Thomas Bryant sidelined with a foot injury. In addition, point guard Isaiah Thomas is dealing with a calf injury.
