Using the amnesty provision on Mike Miller isn't a novel concept: Miami Heat president Pat Riley considered the move last July, and ESPN's Brian Windhorst raised the idea before that in November 2011.
Miami will have to deal with a different type of "Decision" this summer. With increasing payroll obligations and a bump in the luxury tax thanks to the recently enacted collective bargaining agreement, retaining Miller could be an expensive proposition.
Miller is due $12.8 million over the next two seasons, and when you forecast the production that Miami is likely to receive from its 33-year-old swingman over that stretch, the benefits don't appear to outweigh the costs.
There are several pros and cons to exercising the amnesty provision on Miller, and while Miami doesn't appear likely to go down that road, it's safe to assume that the Heat will explore both sides of the argument before making a decision in mid-July.
