And as fate will have it, the Cavs will host the Celtics in their season opener on October 17.
Irving listed Miami, San Antonio, Minnesota and NY as his preferred destination.
Despite competing in three straight NBA Finals - winning one - the Cavs seemed to endure some discord this offseason with Dan Gilbert failing to renew former general manager David Griffin's contract.
David Griffin on The Jump (h/t Ball Don't Lie's Ben Rohrbach): "This is a guy whose list included really good coaching situations - Brad Stevens and Popovich". Boston lost their best answer to what is arguably the best backcourt in the East.
Irving was the No. 1 pick in the 2011 draft.
Zizic as that "filler salary" and no lottery protections on the pick basically make this the super-sized version of that offer.
ESPN's Adrian Wojnarowski also reported that the Cavs were anxious to get Thomas in for a physical to see if they agree with the Celtics' treatment plan, but that they're not concerned. One of those players who was named was Boston's very own, Jayson Tatum.
Cleveland has earned three straight spots in the NBA Finals, winning a title in 2016. The teams will play three times this season - and that is the only time that the Celtics visit Cleveland in the regular season. Both struggle mightily on the defensive end, but are two of the league's best - and highest usage - players on the offensive side.
He has two more years on his contract - $18,868,625 next season and $20,099,188 in 2018-19 - with a $21,329,750 player option in 2019-20. With the addition of Irving, the Boston Celtics look to compete for an National Basketball Association title this season with a legit starting five and a lethal bench.
The Celtics will send Isaiah Thomas to Cleveland as part of a package.
