Nice job so far by J.B. Bickerstaff making the Cavaliers competitive this season. I will really tip my hat to Bickerstaff, though, if his Cavaliers can hang close in this matchup.
Cleveland is riding high with a season-best three-game win streak with the last two victories coming against the Nets. Boston, on the other hand, is in circle-the-wagons mode with a season-worst three-game losing streak. This losing streak has coincided with the absence of Jayson Tatum due to COVID-19. 
There's a chance Boston gets Tatum back for this game. But if that doesn't happen, I still like the Celtics to cover this spread. Zero chance Boston takes Cleveland for granted even though it has won the past eight meetings while going 6-2 ATS the past eight times hosting the Cavaliers. 
There's a great deal of urgency for the Celtics not only to halt their losing skid, but also knowing they play seven of their next eight games on the road, including five games on the West Coast.
