How hard is it to just check your facts? Whis said on "In the Red Zone" that the Cards thought they could pass on these guys effectively. Clearly they came out wanting to pass.
Then, all you have to do is check the NFL.com play charts:
1-10-ARI 20 (15:00) 19-J.Skelton pass incomplete short right to 12-A.Roberts.
3-6-ARI 24 (14:15) (Shotgun) 19-J.Skelton pass incomplete short right to 11-L.Fitzgerald (22-C.Rogers).

3-2-ARI 44 18) (Shotgun) 19-J.Skelton pass incomplete short right to 29-C.Taylor [99-Ald.Smith].
Those are the possessions before we went down by 16 points and have to start passing. That's 11 of 15 pass attempts that are out of shotgun.
Maybe the Cards have a shotgun package that features both a fullback and tight end, or two tight ends.
But I doubt it.
