Honestly the only sign and trade that made sense for Cleveland is the one from Boston which would include NY Knicks from the Ringer.Someone, somewhere on twitter made a good point on the sign and trade thing with Lebron; if Lebron leaves, unless you're getting fantastic assets for him, the Cavs #1 goal may be to duck the luxury tax, so they really wouldn't want to take much salary back. So, it could make a sign and trade hard to make work
Where the Cavs would get whomever the Knicks took at 9 and a first round pick from Boston plus expiring contracts in Kanter and Morris.
The Knicks would get Kyrie and Boston would get LeBron.
I don’t see this one happening though.
I can’t see Houston or San Antonio offering anything to compel Cleveland.
