I understand this is bad versus bad. Only Cleveland is worse than Memphis. The Grizzlies have been playing better and I prefer their young talent over Cleveland's. 
The Cavaliers did win their last game, holding off the Hornets, 100-98, this past Wednesday. But that was just the Cavaliers' third win in their last 19 games. They have failed to cover in 14 of their last 18 games and are 3-8-1 ATS during their past 12 home contests. Only once all season have the Cavaliers won two in a row. 
Memphis is 4-2 in its last six games and very well could be 5-1. The Grizzlies blew a 24-point second-half lead in a 126-122 loss to the Thunder on Wednesday. 
The Grizzlies have covered the last four times they've met a below .500 opponent. Memphis youngsters Ja Morant, Brandon Clarke and Dillon Brooks are all playing well.
