Can you take a step without a dribble?

Answer 1

Yes, you can

^Uh no..

Stepping Before DribblingA player who receives a pass from a teammate and starts running without dribbling is performing an illegal move. The player must dribble before he moves on the court with the ball, or else the referee will cite him for traveling. At the professional level, National Basketball Association referees seem to let players take a step before the dribble, but this should not happen in college, high school or youth basketball.
