Former Celtics star Kendrick Perkins wasn't afraid to share his honest opinion of Kyrie Irving's struggles.

Perkins, who played with Boston from 2003-11 and was Irving's teammate when they were both with the Cavaliers during the 2014-15 season, blasted Irving for his leadership style and said how the guard carried himself was disrespectful to the franchise.

“The way he went about it was disrespectful to the city of Boston, was disrespectful to the organization, and he didn’t represent what Celtics pride is all about,” Perkins said during an interview on FS1's the "Herd with Colin Cowherd." "I spent my first 8 1/2 years of my career in Boston. Those fans are unbelievable. The organization is unbelievable. The history of the franchise in itself is unbelievable.

“The way Kyrie went about it — ‘OK, yeah I struggled, OK on to the next game’ — kinda like the ‘I don’t care’ attitude. Basically throughout the whole process, I mean, I thought he had gotten it. But he was just a bad leader. And he didn’t represent what Celtic pride was about. It was proven that — in my opinion — he’s not a Batman. ... He can't carry his own team."

Perkins' comments come after the Celtics were eliminated from the playoffs early. They lost the Eastern Conference semifinal series against the Bucks, 4-1, and Irving struggled during all five games. He averaged 20.4 points, 6.4 assists and 4.4 rebounds on just 35.6 percent shooting. He made only seven of his 32 attempts from 3-point range.

But when it came to facing criticism, Irving was brief with reporters. When asked about his shooting slump during the postseason, he simply said: "Who cares."

After he went 7-of-22 in a Game 4 loss, Irving explained: "The expectations on me are going to be sky-high. I try to utilize their aggression against them and still put my teammates in great position while still being aggressive. I am trying to do it all."
