JACKSON SHOWED A LOT OF ACTION: While playing more minutes than any of the 25 players who played in Wednesday’s game between the Mavs and Portland Trail Blazers, Justin Jackson was able to show the Mavs’ coaching staff how well he can prosper under difficult circumstances on the road. Jackson played 34 minutes off the bench, scored 21 points and added four rebounds. He also was 8-of-15 from the field and 3-of-8 from behind the 3-point line. It’s the most points Jackson has scored since the Mavs acquired him in a Feb. 6 trade that involved sending Harrison Barnes to the Sacramento Kings.
