You have to be intellectually dishonest or flat out stupid to think that any one (Dansby) defensive player would have made a difference last year. Granted, losing Dansby was a blow, but ABSOLUTELY nothing would have overcome the debacle we had at the QB position. Having a horrible QB in the NFL would be akin to a baseball team not fielding the entire left side of their infield.
That's your and many others opinion. However, the Cards blew two late leads in games that could have turned the entire season. It only took 7-9 to win and they won 5 with those horrendous QBs*.
So it is possible that a one player better Defense could have turned those 2 around and got the Cards in the Division race. Not likely but it could have happened.
(Of course they just as easily could have finished 3-13 if Oakland and Dallas hadn't missed chip shot kicks.)
In addition the Cards were continually behind by 14-21 points before halftime because the Defense couldn't stop any team with a pulse without a turnover. That had to be taking the Cards out of their game plan early and that is never a good thing for an offense especially one with a weak QB corps. Dansby called the Defense. How do you know that it wasn't the change in that area that was causing the total collapse of the defense?
But again its more likely you guys are right and a decent QB will make the difference between last place and first place. I sure hope so because we have a potentially decent QB. We still don't have a Dansby.
*What is really sad is that Somers was blogging from camp around this time last year about how inaccurate Anderson had been and that DA wasn't pushing any QB on the roster let alone Leinart.
