The Grizzlies have won five in a row since their star point guard Ja Morant suffered a knee injury. How are the Grizzlies doing this without their best player? Defense. Memphis has held its last five foes to an average of 90.2 points.

The Mavericks have short revenge for a 97-90 home loss to the Grizzlies from last Saturday. Dallas was without Luka Doncic and Kristaps Porzingis in that loss. Both are expected to play here. Dallas is in stop-the-pain mode, too, losers of eight of its last 10.

Doncic is a superstar, but the Mavericks are a defensive-minded team. They rank 25th in scoring, but give up the 12th-fewest points. Dallas has a great history of going Under in an underdog role with the Under cashing 22 of the past 30 times.

I'm looking for another tight defensive battle here.
