The offensive player gathers the ball while on his right foot. He then takes
a step with his left foot (step 1) into a hop step, landing first with his
right foot (step 2) and then illegally with his left (step 3). We missed
this one - it is a traveling violation.
簡單來講，裁判就認為哈登左腳(Step 1)墊步之後的落地沒有雙腳同時落地啊，但是哈
登這招很多年了，所以我才會認為是裁判算成同時落地所以過去都沒有吹判啊。裁判現
在突然清醒要這樣判，我希望以後都能保持同一套標準啦。
另外來看一個合法的雙重後撤步，這個就很標準沒有走步了。
