I understand the Wizards play no defense, but have the capability with Bradley Beal and Russell Westbrook to light up the scoreboard thus proving tough to make an Under work. 
But there are enough factors here to feel confident that this total has been set too high. Beal was the only player from either team to play in last Sunday's All-Star game. All the other players haven't played in six days. That's just too long to go between games without there being a rust factor. 
Washington hosted Memphis eight days ago. The Grizzlies shot 49 percent from the floor and won, 125-111. The Wizards made 51 percent of their field goals. Beal and Westbrook both played. Yet the combined score came out to 236. This total opened higher. 
The Grizzlies have given up 112 points or fewer in five of their last six games despite playing the Mavericks, Clippers twice, Bucks and Wizards during this span. Memphis ranks eighth in the NBA defensively allowing 110.8 points. 
The Wizards have scored 116 points or fewer in regulation in five of their last seven games. They have given up fewer than 118 points in four of their last five games. The Under has cashed in seven of Washington's past nine road contests.
