The Rockets, seeded second in the play-offs, endured a disappointing end to the regular season with three successive defeats and have lost back-to-back games at home.
Ime Udoka’s side are featuring in the play-offs for the first time since 2019-20, when they lost against the Los Angeles Lakers in the semi-finals.
“I wouldn’t say the moment, I would say the physicality at times, going after guys, and just play-off basketball,” Udoka said when asked if a lack of experience cost his side.
“It’s not really about the moment. Going into the lane, trying to shoot over too many and not finding your outlets is a big thing and a big key for us all year.”
Elsewhere, the Cleveland Cavaliers sealed a 121-100 win against the Miami Heat in the Eastern Conference play-offs.
Donovan Mitchell scored 30 points with Ty Jerome adding 28 points and Darius Garland scoring 27.
Jerome, who picked up 16 of his 28 points in the fourth quarter, was making his play-off debut.
