You cant take three or more steps without dribbling the ball or else it is ruled as a traveling violation and will result in a turnover in the NBA.
If someone has a ball and they take two steps without bouncing it, it is traveling.
Dribbling my hommie.
It is impossible to travel when inbounding. While there are space restrictions for a throw-in, the thrower is not required to maintain a pivot foot or observe any of the other restrictions of the traveling rule.
