As a restricted free agent, Cook can field offers from any team with the Thunder owning the right to retain him by matching the offer. Cook's salary last season was $2.1 million. "He's matured a whole lot from last year to this year, just his whole outlook," said Conley, father of Memphis Grizzlies point guard Mike Conley and a former Olympic gold medalist in the triple jump who coached Cook on a powerhouse AAU team that included his son and Greg Oden.

Cook returns to Oklahoma City Wednesday to participate in a Thunder basketball camp.
