Kendrick Perkins is a great follow on Twitter. The former Boston Celtics center, who was on the 2008 NBA Finals-winning team, is not afraid to give his honest opinion on basketball-related matters, and his tweets after Monday night's playoff game are evidence of that.

The Celtics lost 113-101 to the Milwaukee Bucks in Game 4 of their Eastern Conference semifinals series and now stand on the brink of elimination entering Wednesday night's Game 5 at Fiserv Forum. Perkins was critical of his former team shortly after its latest loss at TD Garden, calling out the C's for showing no heart and playing selfish basketball.

He was back at it Tuesday morning, this time with criticism of Celtics guard Kyrie Irving.

Irving has struggled against the Bucks, there's no doubt about it. He played well in Game 1, leading the Celtics with 26 points in their only win of the series so far. Since that victory, Irving is averaging 20.3 points while shooting 30.6 percent (19-for-62) from the field and 20 percent (4-for-20) from 3-point range over the last three games.


Perkins' "Batman" comment is interesting. This implies Irving isn't a real No. 1 star on a championship team, and it's not a crazy take, either. The veteran guard has shined on the NBA Finals stage as a member of the Cleveland Cavaliers, but all of that success came as LeBron James' best teammate. Irving has yet to show he can lead a franchise to championship glory as its best player. 

The Celtics' season isn't over yet, but if there's any chance for a historic comeback, it has to start with Irving in Game 5. It's difficult to imagine the C's mounting a comeback if Irving doesn't perform at a superstar level.
