Ken Berger of CBSSports.com reports that the Cleveland Cavaliers are actively pursuing cap room for a max contract offer, presumably with LeBron James in mind: 

The Cavaliers, meanwhile, have engaged several teams in trying to find a taker for contracts in a possible multiteam trade in which they would dump Jarrett Jack's $6.3 million salary to clear a max free-agent slot, league sources told CBSSports.com. In one such scenario, according to Yahoo Sports, the Cavs would send Jack to the Nets while trying to find a third team to take Marcus Thornton, who is owed $8.6 million next season.

Berger reported Monday that the Cavs reached out to the Hawks about a potential deal but the Hawks don't have interest in Jarrett Jack. 

You would imagine a sign-and-trade for Deng could persuade the Hawks to send something else out to the Nets in exchange for Jack. But the bigger point is that Cleveland is actively looking to create room for James. 

If James, whose agent has reportedly already met with Dan Gilbert, decides to return to Cleveland, they'll have to act fast. Clearing Jack shouldn't be much of a problem even after signing him to a free agency deal last year. He still has good value as a veteran point guard. But the Cavs are probably going to want a veteran point guard at some point behind Irving even if they sign LeBron. James is pretty familiar with a lack of point guard depth after last year with Miami. 

The Cavaliers are reportedly not keen on moving Anderson Varejao, and that's going to take up some cap space. But this gets lost in the ideas of James going anywhere: you have to build a team around James. Making room for his max contract is just the first step.
