NFL meeting to ban hip drop tackles.. (Update: Now banned)

GOOD!!!!!!!

That type of move is NOT tackling!!! It's a lazy shortcut to bring the ball carrier down by any means necessary. The over reaction to this decision is just that. Hip drop tackles are not a common occurrence during a NFL game, you may see one happen out of 16 games played. The players are not coached to perform this move and it's great that the NFL have moved to rid this RARE move from the game before it became commonplace. (y)
In this situation, I still think that Tom Brady is more right than he isn't. Who is teaching offensive players how to protect themselves? But the defensive player is supposed to worry about protecting both themselves and the offensive player...

My question is once they pass a defensive player, is the defensive player out of the play? I would love for someone to explain the tackling technique for bringing down somebody running full speed from behind.
