Cavs had a deal in place to acquire Paul George from the Pacers in June

According to Brian Windhorst of ESPN, back at the end of June the Cleveland Cavaliers had a deal in place with the Indiana Pacers and the Denver Nuggets to acquire Paul George. Despite the fact that deal was agreed on by all sides, Pacers GM Kevin Pritchard decided to back off from the deal at the last minute, as Windhorst explained in his piece:

"On the afternoon of June 30, the sides thought they had a deal. On a conference call between the teams, everyone tentatively agreed. George to the Cavs, Love to the Nuggets, Harris and other pieces to the Pacers, sources said.

Plans were put in place for a call to be arranged between George and Gilbert, an important step before the trade would become final, sources said. The front office began making other plans to complement George as free agency was about to begin.

But then Pritchard, who had been on the conference call when the deal was tentatively agreed to, sent the message that his team was backing out, sources said. There was no deal."
