Ok, instead of dismantling the Knicks, lets try to fix them a bit for next year, since they don't look ready to really compete this season.
The Fournier experiment is not working but he is the kind of guy the Cavs could really use - a wing who can create a shot and hit from 3. Kemba is not a starter but is good enough to play back up.
The Cavs will likely lose Sexton and Rubio next year, so why not play the long game. And Sexton is gone for the year. They get assets they can control in Fournier and Kemba, along with a young guard and a couple of picks.
Sexton could be an offensive force for the Knicks in the backcourt for the future. Rubio is a solid backup rental, behind some combo of Quickley and Rose.
