Without logging into that site and providing feedback …. I’d give this rumor a less than 5% chance of being substantial.

Z’s contract may be expiring, but the organization and LeBron have both stated they want him on the team, and he wil retire as a Cav.

The Cavs will not want to take on that long of a deal either. Jackson is very good, but dealing Z would really hurt the frontline depth the Cavs currently have.

This just sounds like somebody who was playing with the trade machine and came up with this scenario. I seriously doubt Ferry has had any conversation with Golden State on a deal like this.

Should the Cleveland Cavaliers trade Zydrunas Ilgauskas’ expiring contract for Stephen Jackson (+ Devean George or Acie Law or some other contract filler)?

No.
