2) His footwork has been poor.

What's wrong with Philip Rivers' arm strength? That was a question I was asked numerous times following Monday night's game. He floated two deep balls that were picked off and he also had two underneath routes that were undercut for interceptions. However, after studying the tape, I came away more concerned about his feet. He has developed two very poor habits. Most NFL passing plays require the quarterback to release the ball in rhythm (immediately after his third, fifth or seventh step) or with a single hitch step. In this game Rivers double- and triple-hitched after he completed his drop and he was repeatedly late on throws. Also, he struggled to reset his feet when he was forced to move around inside the pocket to avoid pressure. Until he fixes these two issues, his timing and accuracy will continue to suffer.
