Theis, who turned 29 this month, is in the final season of a two-year, $10 million contract. If he’s available at that price, the Bulls potentially could bring him back, but he might be due for a raise on the open market. The Bulls will have to get creative to find ways to improve the roster in the offseason, but they do hold Theis’ Bird rights, which would allow them to exceed the salary cap to re-sign him.
