The ruling was that Cruz gave himself up and therefore the play was dead.
I didn’t see anything to suggest that Cruz gave himself up. The reason he fell was because he tripped on his on feet, not because he went to the ground voluntarily.
In my opinion it was a blown call.
On the next play Eli Manning throws a TD strike to Hakeem Nicks, the Cardinals fail on 4th down, game over.
This will be hotly debated and I will tell you why, if Cruz would have gotten up and ran in the End Zone I am 100% sure they would have called it a touchdown.
The Cardinals were screwed point blank, period.
