On-air drills and negative transfer

I recorded the above video about negative transfer as a reaction to a Twitter dialogue based on the video below. After he said that he will use "anything and everything in the gym" to make the drill game-like, except defenders, and said that he wished that his garbage can had wheels, I had to respond.The belief in these drills, and others like them, is powerful and persistent. However, how does creating an obstacle course on the court make a drill game-like? How many players play against stationary garbage cans or throw passes through hurdles? Why can't trainers/coaches use defenders, even guided defenders, to create some game-like conditions?By Brian McCormick, PhDDirector of Coaching, Playmakers Basketball Development LeagueAuthor, The 21st Century Basketball Practice and Fake Fundamentals
