In the match which Durant and Harden both were absent, Nets were defeated by Trail Blazers 128-109 away. Irving's 28-point effort wasn't enough for a win. Nets already guaranteed the 1/8 finals. But this was a critical win for Trail Blazers as they still have a big chance to qualify for 1/8 finals.
Nets is the underdog against the Trailblazers, the line open up at -6.5 and I'm sure many gamblers took the odds because that's already attractive and Portland covered it with more spare. And it's Irving vs CJ and Dame Time so obviously Portland really take care of it and this is a must win situation for them.
Yes they do. Let's take a look at the Western Conference standing.

Mavs has a game tomorrow against the Wizards and there is a high chance they may lose it if they don't work hard.
Wizards badly need that win too. Kristaps Porzingis and Josh Richardson are back for the Mavs but the Wizards had won 11 of their 13 games.
I think this will be a close game with a little spread difference.
Lakers are also on the edge to be pushed to 7th position which is not a good thing when AD and Lebron just came back. They will need that rest before the playoffs to fully heal and have their A game.
Looking at schedules, Mavs has the easiest among the 3 fighting for the 5th and 6th spot.
