Morris comments came after the game, in which the Suns only managed a franchise-low 24 points in the first half, and nearly set a team record for fewest points in a game.
Of the loss, Morris commented: "Every night is not going to be a great night. It's going to happen. Stuff like that is going to happen. We expect more from [our fans] because I know they expect more from us."
More, from the USA Today story:
"I don't think we have a home-court advantage," Markieff said. "It does not feel like a home-court advantage at all. Some games are going to be bad. You can't win every game. That comes along with sports. Nobody wins games. We need the support. We need, as a team, to know that our fans are going to be behind us and I don't feel like this year they're behind us enough.
"I feel like we do have those genuine Suns fans but, for the most part, I feel like we had more San Antonio than Phoenix fans tonight."
Morris went on to emphasize how he and his teammates need their fans "heckling" opponents such as "the LeBrons" and "D-Wades." He lamented that beyond the first few rows of fans at Suns games, it feels like fans, "were just at the game, just watching," instead of cheering.
The Suns rank 22nd in terms of average total fan attendance (16,669) and 23rd in average percentage of seats filled (90.5 percent), according to ESPN.
Morris, in his fourth NBA season, is averaging 15.1 points per game for the Suns and is the team's fourth-leading scorer.
Phoenix is 31-29 and currently two spots out of playoff contention in the NBA's Western Conference.
