Kyrie Irving explained why it's so difficult to play with LeBron James.

"It’s definitely a challenge,”he told ESPN. “You now become part of a championship-caliber team based on a unique talent. LeBron is so smart, so talented, such a strong leader. And you’re trying to implement who you are and grow as a player and learn every single day. And it can be difficult because it demands a lot of you."

“Certain times young players — and even older ones — find it a big transition, because you’re playing a certain way and growing as a player and you have a vision of what your career will look like," he added.  "And then this player of such great stature arrives, and you’re still trying to be great, and he’s already great ... It was a lot for me to figure out."

Despite that, Kyrie and LeBron achieved major success together with the Cleveland Cavaliers and brought the city a Championship in 2016 before heading to the Boston Celtics and Los Angeles Lakers, respectively.
