Parcells killed him. BP has instilled this fear into JJ to "trust the play" and go to where the hole is supposed to be, even if it's not there. Bp is so afraid of negative plays, that he's taken away JJ ability to improvise. As a result, JJ rarely bounces outside as he did his 1st year. Chuck Knox Jr. was critical of JJ not being able to see alternate holes when running. Funny, JJ had no problem finding the holes his 1st year. BP has changed JJ from a free-running back that could improvise and bounce outside, to a straight-ahead runner. While this may not lead to many negative yardage plays, it means a lot less homerun plays that result when you run free.
