He even apparently provided a list of teams he prefers to join.
Chris Haynes of ESPN:
That’s quite an eclectic mix.
The Knicks play in a major market near Irving’s native New Jersey, but they’re lousy. The Heat have a merely good team, excellent basketball culture, beautiful weather and a state with no income tax. The Spurs also offer a great basketball culture and no state income tax – plus Gregg Popovich and Kawhi Leonard. The Timberwolves are an up-and-comer with multiple players – Karl-Anthony Towns, Andrew Wiggins and Jimmy Butler (a friend) – on Irving’s timeline (though one would likely have to be traded for him) and a coach in Tom Thibodeau who worked with Irving through USA Basketball.
But Irving doesn’t possess a no-trade clause. Cleveland can trade him anywhere – or not at all.
Teams that Irving greenlights might offer more than teams he doesn’t, believing he’d be more likely to re-sign when his contract expires. But his free agency is still two years away. It doesn’t seem that will play a huge factor.
For Irving to work his way to a team he prefers, it will take a little luck in which team offers the Cavs the best package – or impressive finagling by his agent.
