J.R Smith and Carmelo Anthony go way back. Both NBA players played for 5 seasons in Denver before leaving for New York to play with the Knicks. 

With the Knicks going through various changes with their coaching staff, it seems like Melo will reportedly leave the Knicks and test for free agency during the off season. Smith, however, is not feeling Melo's possible decision and recently revealed his displeasure through a tweet response with a fan.
