Over the past few days, Cetlics fanboy  BillSimmons has been heavily critical of NBA players like Landry Shamet and Devin Booker for skipping out on playing for Team USA, in favor of workouts at open gyms.

As Simmons says, these open gyms are useless and can’t compare to the training one would get from a real game.
