The 29-year-old was clearly not happy with his side’s performance as they lost 114-110 at the Staples Center.
The Timberwolves are now 4-8 and seem unable to stop their current losing streak, which is now four-games.
Butler believes the team’s lack of rebounding is a fundamental part of their recent poor form.
“To know that we were that close and all we got to do is rebound the basketball,” Butler said after the Lakers game.
“That’s been the story for us thus far, we have been right there, we’ve been out rebounded.
“We have to figure out a way to go get the ball.”
The Lakers finished with 47 rebounds to the Wolves’ 40, and the side from LA topped both offensive and defensive rebounds stats.
Butler didn’t pull any punches in his assessment of the Timberwolves’ performance after the game.
They are now 13th in the NBA’s Western conference and Butler feels this position is completely justified.
“I don’t believe in luck,” he said.
“I think everything happens for a reason. We played good, four games. We played bad, eight games.”
It is unclear how his Timberwolves teammates will respond to Butler’s comments, especially after he has already made it clear about his desire to leave the organisation.
Butler, who requested a trade during the offseason, admits it’s still early in the season, but is concerned about using that as an excuse.
“The season is still young but we can’t use that for too much longer, because these games come around quick,” Butler said.
“We know what we have to do. I’d like to say it is going to be better the next game.”
The Timberwolves next game is against the Sacramento Kings on Friday.
