Kyrie Irving has officially opened up about the pressures of playing with LeBron James.

On Friday, while on the Bill Simmons Podcast, the Boston Celtics point guard labeled it as “really tough” to play with The King, via HoopsHype.

“I went from being in Cleveland to having half the fans show up to now ‘Bron shows up and now every night is packed, every road game is like a home game for us. You think of the media attention that comes with all of that and the elevated pressure of, ‘Now it's championship or you fail.' And then you gotta figure out how you fit within the system. Basketball is a systemic game. How do you build that strategy and how do you fit in with that? And it was tough.”

Irving, 26, played three seasons with LeBron in Cleveland from 2014-15 through 2016-17. Of course, the crowning moment came during the Spring of 2016 when he, James and the rest of the Cavaliers overcame a 3-1 series deficit to the Golden State Warriors.

Kyrie's critical three-point right-wing-extended bucket propelled his team to championship greatness.

After asking for a trade (which ultimately landed him in Boston with the Celtics), he's now LeBron's enemy on a terrific squad. In 60 games played this past season, Irving averaged 24.4 points and 3.8 assists while shooting a solid .491 from the floor. His late-season injury prevented him to suit up for the NBA Playoffs, but with an excellent young core and Gordon Hayward eventually on the mend, he's currently in a terrific place.

Now that he's admitted it's tough to play with the greatness of James, nothing much is left between the two former teammates.
