This was a good article, but I would dispute one point that Caccitore made, and that would be about the sustainability of turnovers. While everyone seems to lament the Cardinals lack of a pass rush, the only person who really counts DOES NOT. That would be Bruce Arians, who has flat out said that he does not want to sack the QB. He wants to keep stacking our secondary with gifted playmakers who have the knack for creating turnovers which creates not just huge advantages in field position, but also enhances his team's chances of scoring pick sixes.
Arians has obviously set his sights on getting just enough pressure on the opposing QB, to create just enough hurry so that slightly erratic throws can be picked off by the large numbers of safeties and corner backs that Arians keeps on the field at any given time. While every other Head Coach is concerned with sacking the opposing QB, BA believes this to be much lesser achievement than stacking his secondary and shooting for turnovers. His, (contain the run and pick off the pass) philosophy seems to be working very well, and may in fact be quite sustainable if the D-Line can get just enough pressure on the QB to hurry his throws just a little. This is going to be interesting to watch as the season progresses.
