Setting aside the hugely disappointing injury, how would a ref call that a travel? That kind of hop step is standard in the NBA. At speed or even slowed down it looked fine, so I'm curious what I'm missing. https://www.espn.com/nba/story/_/id/29586366/magic-forward-jonathan-isaac-torn-acl-left-knee He's basically doing the same as this (a guy demonstrating the Derrick Rose hop step): https://www.youtube.com/watch?v=4eWtplFaKGs . Wondering what stood out to the ref that made him blow the whistle.
