Maybe. I would imagine everyone but JV is a likely candidate to be moved now.
Only reason why JV is likely safe is because he has shown his floor to be an average to slightly above average NBA centre - the hardest position to fill in the NBA.
Thing is its hard to blow it up and except playoffs next year. The way I see it you 3 position talent wise that are at least top 15 at their position. Lowry, Rudy and Jonas. You just have to fill the holes.
