The Boston Celtics head into Sunday’s matchup at the Portland Trail Blazers looking to extend their recent winning streak, while Portland grapples with a lengthy list of absences and a losing streak that they'd like to snap. Both teams have had very different seasons, with Boston sitting comfortably above .500 and Portland struggling to find consistency for the year. Here, I break down this inter-conference matchup in the NBA and give you my Celtics vs Trail Blazers prediction for Sunday.

I am projecting a convincing win for the Celtics in this contest from Moda Center. The Celtics have been more consistent on both ends of the floor lately and that trend should continue here against a Trail Blazers team that has not been able to take advantage of their opportunities in three straight home games. I'll lay the points with the Celtics on Sunday.
