On March 20, 2015, Aldridge became the Trail Blazers' all-time leader in rebounds by recording 10 against the Orlando Magic. Meanwhile, however, the Blazers were cooling off after a 30–11 record through the first 41 games of the season when shooting guard Wesley Matthews, whom Aldridge called "the heart and soul" of the Trail Blazers, tore his Achilles tendon on March 5 against the Dallas Mavericks and missed the rest of the season and playoffs. The Blazers subsequently went 21–20 through their final 41 games. In the playoffs, the short-handed Blazers were outplayed and outmatched by the Memphis Grizzlies in five games. Aldridge averaged a career-best 23.4 points per game, made a league-best 659 field goals, and was voted onto the All-NBA Second Team.
