On the final, it was an excellent toss by Rothy and equally excellent catch by the reciever.
That having been said, why did AZ have 3 players near the vicinity, but no one close enough to even bother the catch? Who were the other two guarding?? Lets recapp. AZ stopped Pitt on 1st and goal from the 6. You've got to figure Pitt is going to pass on 2nd down and 6. You can choose to blitz or not. Since AZ chose not to blitz, that means that had 6 guys (7?) to cover the endzone. Completely unacceptable to let a corner endzone route go basically uncovered when you've dedicated 6 guys back (7?) and have 3 of your defenders in the vicinity of the reciever.
Now as to the final drive:
Cardinals had Pitt 1st and 20 with 88 yards to go for the touchdown. Yet in only 5 plays Pitt is at 1st and goal from the 6. None of the Pitt plays were spectacular IMO, altho the finale was a perfect toss and catch. AZ chose to not blitz and it cost them.
That is some serious Prevent the Win D.
