Boston forward Marcus Morris could not hide his frustration after the Celtics blew a 28-point lead to lose the LA Clippers on Saturday.
Boston appeared to be cruising to their 36th win of the season before the Clippers - inspired by Landry Shamet making four three-pointers in the fourth quarter on his debut - completed the largest comeback in the league for two seasons.
The Celtics, who also gave up an 18-point lead against the Los Angeles Lakers two nights earlier, lost Kyrie Irving to a knee injury late in the second quarter.
But Morris was not in the mood to make excuses and complained that it was not fun being on the team at the moment.
"For me, it's not really about the loss, it's about the attitude that we're playing with," he told boston.com
"Guys are hanging their heads. It's not fun. We're not competing at a high level. Even though we're winning, it's still not fun. I don't see the joy in the game."
"I watch all these other teams around the league and guys are up on the bench - they're jumping on the court, they're enjoying their teammates' success.
"They're enjoying everything, they're playing together, and they're playing to win. And when I look at us, I just see a bunch of individuals."
Morris started and scored 15 points and had six rebounds in the loss, but said if a move to the bench helped the team, he'd be all for it.
"We have to genuinely want to win. That has to be the first goal. Whatever that takes, I'm with it. If they want to take me out of the starting lineup, get some juice in there, I'm with it. I'm trying to win."
One boost for Boston is the news that the injury to Irving is not serious.
The 26-year-old, who left the game with 2:28 to play in the second quarter and with Boston holding a comfortable 20-point lead, had an MRI on Sunday and he is now listed as day-to-day with the injury.
