From Fischer’s article:
League sources say Washington and Utah are actively exploring the market possibilities with Jonas Valanu010diu016bnas and John Collins, respectively. Chicago has likewise invited trade interest in center Nikola Vuu010deviu0107 for weeks.
John Collins has had a breakout season for the Utah Jazz this year. So good that Utah has had to be extremely conservative with his minutes and injury. Collins is shooting 52.5% from the field, 43.8% from three, and 86.7% from the free throw line, which is a huge improvement from last year.
