Harrison WAS penalized 15 yards for that stupid move, he was lucky he wasn't ejected for that. Overall it was a GREAT game, both teams showed respect for each other and there was no cry babies and excuse makers "on the field", but they WILL show up in the overall NFL fan base, happens every year no matter who plays or who looses.
I stand corrected here, although Harrison WAS penalized it turned out to be only for about a 1/2 yard since the Cards downed the punt within the two yard line, so it could only be half the distance to the goal line.
As far as reviewing the last play, witnin the last two minutes a coach cannot (why? dumb part of this rule) challenge even if he does have a challenge left. The officials up in the booth must "buzz" down and halt play for an on field review. They later said they indeed did review (from the booth) and determined that the field call was correct. But I will AGREE with the fact that this play should have had an on field "official" review because of it's significance. However again, even if the rules would have allowed the Cards to "flag" the play, the coach couldn't have because they had already used all their time outs. If you have no time outs remaining you cannot challenge.
All I know is, I've been a STEELER fan for 40 seasons, the 69-70 season and those first couple years were humbling to say the least, but through thick and thin they have always bust their butts trying. BTW, it also was announced that Sunday's Super Bowl was the most watched ever, beating last yeas game by just a few points in the ratings.
