The basketball world was turned upside down on Friday as free agent shooting guard, Ray Allen, decided against returning to play for the Boston Celtics and instead agreed to play for the rival Miami Heat.

Miami is coming off of their second NBA Championship last month and are now looking to retool their roster for a run at a repeat.

Lewis last played for the Washington Wizards and was involved in a trade with the New Orleans Hornets but never played there as the team subsequently bought him out of his contract, making him a free agent.
