When your DL has so much raw talent and is applying big pressure most all game, no other team will get many chances to throw deep on is. JDR is pretty much garbage, and without the all world DL he has, his schemes have routinely been exposed.
As for Howell, he held the ball too long, too often. As
@WetHog pointed out, some of those sacks were just on him. But its his 2nd NFL start, he gets a break there. Howell clearly has NFL QB talent, he just needs more time in the offense to make quicker decisions, and a play caller who doesn't leave him out to dry in week 1. They should have been running the ball down the Cards throats all game long, not just when they had the lead late.
