As far as the 100yd pick 6 was concerned, there's a good article here http://sports.espn.go.com/nfl/playof...reg&id=3877912
about how Harrison was supposed to rush on the blitz package, but his instincts took over and he dropped pack into coverage and made an incredible play. For the record it was a beautifully designed play by Arizona, because Boldin was open if not for Harrison's ad lib.
And please don't have your sensabilities offended by Harrison's personal foul call just because of announcers' hyperbole. Much worse than Harrison's Ric Flair-chop occurs in many pileups and nothing gets called. Ever. Harrison's personal foul was the correct call; just realize that it was small potatoes.
Cards are worthy, Fitz is the next Jerry Rice, Warner's the real deal, and the Steelers have more Lombardi's than your team.
