Rob Gray, from Caledon, Ontario, is a professor at Arizona State University where he specializes in perceptual motor skill development. His recent book "How we learn to move," available on Amazon, may very well be what he wrote on the cover: A revolution in the way we coach & practice skills. While his work in Arizona has been primarily in soccer and baseball, in this podcast he seemed pleased to delve into hockey and the myriad of timeworn traditions about how we teach and practice the game he played so much himself growing up. His own podcast, The Perception and Action podcast, can be found at perceptionaction.com.
