From Rotoworld with Rotoworld comments:
Steven Adams, Andre Roberson and Dennis Schroeder are "all very available at the moment," according to Jake Fischer of Sports Illustrated.
The Thunder are looking at a massive luxury tax bill next season, so they will look to dump some salary. Obviously, Adams is clearly the most valuable piece, but he's essential to the OKC defense and trading him would likely hurt them in the standings. It'll be tougher to dump Schroder and Roberson, especially after the Hawks and Nets set a fairly high price with the Allen Crabbe salary dump this month.
