5. Irving has played with LeBron before and won
The most obvious reason for a reunion between LeBron and Kyrie is simple. Kyrie and LeBron have won together and reached the pinnacle together.
They were able to come back from a 3-1 deficit to beat an all-time great team in the Golden State Warriors in 2016. They each knew when to dominate and defer, and it led to a pairing that caused the Warriors enormous problems over a seven-game series. The Warriors were able to overcome the Cavaliers in the next season with the addition of All-World small forward, Kevin Durant, who went on to win the Finals MVP.
With Kevin Durant seemingly having one foot out the door according to Chris Haynes of Yahoo Sports with his eyes seemingly set on New York, this is the ideal opportunity to get the band back together and see if they can once again beat the Golden State Warriors and reach the promise land.
