Leading by six with under 30 seconds to go, the Rockets were on the verge of their first victory in their first-round series against the Lakers.
Instead, they fell apart and eventually lost 112-108 in overtime Friday night and are on the brink of elimination.
"Horrendous mistakes," Rockets coach Ime Udoka said. "I don't know if you want to say youth or scared of the moment or whatever the case."
Houston struggled at times to close out games in the fourth quarter during the season, and the problem continued Friday night.
"It's obviously a weakness of ours to close out and finish," Udoka said. "The amount of mistakes or the type of mistakes are egregious, and you can't have those."
This is the second straight playoff trip for the Rockets after they returned last season for the first time since 2020. They were eliminated in the first round in seven games by the Golden State Warriors.
Having that playoff experience, Udoka doesn't see any excuse for their collapse Friday night and had a message for his team.
"Grow up," he said he told them. "You're not that young anymore."
