We knew that Boston and Cleveland had talked previously about a possible Kyrie Irving trade, but the talks had gone nowhere because early on the Cavaliers were asking for recent No. 3 pick Jayson Tatum, along with a veteran player and a pick. Boston GM Danny Ainge had just traded the No. 1 pick and taken Tatum after that step back, no way he was going to move the Duke star.

What changed and got the deal done was the Cavaliers stopped asking about Tatum, said Shams Charania of The Vertical at Yahoo Sports in an interview on NBA TV.

“The big discussion point with Boston and Cleveland over the past several weeks on a potential deal has always been about Jayson Tatum’s involvement. The Cavaliers coveted him greatly. I think if Tatum was involved the first day these talks transpired, this deal would have been done weeks ago.”

What Cleveland got by opening their mind to other possibilities was an All-NBA point guard in Isaiah Thomas, a 3&D guy they needed in Jae Crowder, and the highly coveted unprotected Brooklyn Nets pick for the next draft.
