Traveling in the NBA - Have the rules changed?

Many people have wanted me to point out LeBron's traveling violations prior to him complaining about supposedly not getting a call, however it's become more complicated than that since people now claim several things have happened: That the NBA changed the rules, that there is an extra step allowed, that the rules have stayed the same and it's always been a third step called a gather step, etc. So I compared old footage to new footage to get a better understanding of the gather step. 00:00 Introduction 00:25 Have the rules changed?
