1) arizona has no run game
2) pittsburgh has the best run defense in... well, awhile
3) if you pass from the "inch" line, you have very little time to operate with
4) if you pass from the "inch" line, you are going to be running like 5 seconds off the clock MAX on each pass play
5) james harrison 100 yard INT
6) arizona's defense had effectively shut down the steelers offense since the first quarter (it had been 10-7 and pitt had the pick 6 plus one FG from a drive that stalled with about 6 plays inside the five yard line)
7) arizona would be protecting a FG lead, meaning the defense is most likely either ending the game or sending it to OT where you have all the momentum
i think thats about enough for me. i dont buy your logic at all. arizona's defense really stepped it up this postseason, but with a championship on the line, they simply couldn't make one final stop. it was that, and not the decision to not stop inches from the endzone, that cost them a title.
