Hassan Whiteside cannot wait to become a free agent. The Miami Heat center - for now, anyway - becomes a free agent on Friday and if all goes according to his plan, that will also be the day that he decides where he'll be playing next season. The Heat have said retaining Whiteside is a huge priority, and it's believed that Dallas and the Los Angeles Lakers will also be among the teams who will be courting the NBA's reigning blocked-shot champion.
