07:04 AM ET 07.19 | Miami Heat swingman Mike Miller became a free agent Thursday, and his next destination awaits. Multiple reports Thursday said Miller is interested only in joining a championship contender, adding that the Thunder is considered to be the front-runner. A person with knowledge of the situation said Thunder general manager Sam Presti is scheduled to fly to Miami to meet with Miller this week. Because the Thunder's payroll is pushing up against the $71.7 million tax threshold, Oklahoma City would be able to offer Miller only a minimum contract for roughly $1.4 million. Under normal circumstances, that number might be enough to send the Thunder into tax territory. But a provision in the NBA's collective bargaining agreement could come into play.
