His former team (the Golden State Warriors) had a chance to match the offer but they declined.
The day the Cavaliers signed Patrick McCaw, they had nine healthy players available for a game that night in Miami.
A person with knowledge of the situation told The Associated Press on Tuesday that the league has opened a review at the request of the Golden State Warriors, the team with which McCaw spent the previous two seasons.
McCaw is now slated to become an unrestricted free agent.
Suspicious packages sent to up to 14 diplomatic missions in Australia
It was not immediately known which countries' diplomatic missions in the national capital, Canberra , were affected. However the USA embassy in Canberra was not targeted with a package, a spokesperson said.
According to The New York Times' Marc Stein, the National Basketball Association will investigate the situation at Golden State's request.
The Warriors declined to match McCaw's offer sheet almost seven months after rejecting their $1.7 million qualifying offer and two-year, $5.2 million deal, which included a non-guaranteed deal his second year. It's unclear how long the NBA's review will take, or what - if anything - the Warriors are seeking. Without knowing for sure, it certainly looks like a predetermined move by the Cavs and McCaw to get him out from under the Warriors' control and able to seek out a deal wherever he can find one, without that team anxious about their offer being matched. He scored 5 total points in the three appearances with the Cavaliers.
McCaw was originally selected by the Milwaukee Bucks in the second round of the 2016 NBA Draft but was immediately traded to the Warriors for cash.
