I don't like this for the Cavs even though you get someone locked in to LeVerts role at LeVerts price with championship pedigree.
There will be some people I think though that won't mind this since Klay is an off ball shooter, LeVert could be leaving in FA anyways and only a srp and Merrill also given up
For Mavs to get Grant, they pretty much have to salary wise trade Klay and PJ The scoring punch of grant would be ideal for their starting lineup
Trail blazers get a younger PF thats cheaper, light picks and an expiring deal sign them up!
