Former Boston Celtics big man Kendrick Perkins has never been shy about sharing his feelings on all things basketball. The 2008 NBA champion turned ESPN analyst regularly brings the heat on television as well as social media with a seemingly endless flow of hot takes.

Earlier this week, it was Celtics star Jayson Tatum that got caught in his crosshairs. As relayed by Heavy.com’s Vinny Somma, Perkins tweeted that Tatum had the “body language and energy level of an underpaid player” despite the fact that the All-Star forward inked a massive contract extension in November.

On Thursday, the 14-year NBA veteran was back at it again with another Celtics-centric hot take.

However, rather than use his platform to criticize the current club, this time he backed one of his former teammates as an all-time great.
