Great Superbowl! Enjoyed all 30 minutes of the second half. I must say, Jennifer Hudson is now squarely in second place for all time renditions of the Star Bangled Banner, only being edged out by Whitney Houston. Anyone catch President Obama's short interview with Lauer before the game? That must be unprecedented, also pretty interesting that he wasn't trying to play the middle of the road on who he was picking to win, considering the entire Steelers organization basically canvassed and supported his election bid in the state of Pennsylvania, while the other team was the home state organization for his rival. No brainer, huh? Overall I thought the commercials weren't as good this year as previous years, although I thought there were some pretty notable ones, including the etrade babies with one of them singing "broken wing."
A challenge can only be made on certain reviewable calls before the two minute warning and only when a team has at least one time-out remaining in the half. When a coach decides to challenge a call, he throws a red flag onto the field, indicating the challenge to the referees. Up until the 2005 season, coaches could also signal a challenge via an electronic pager, now used only by the replay assistant.
The referee has 60 seconds to watch the instant replay of the play and decide if the original call was correct. The referee must see "incontrovertible visual evidence" for a call to be overturned. If the challenge fails, the original ruling stands and the challenging team is charged with a timeout. If the challenge overrules the previous call, the call is reversed with no loss of a timeout.
After the 2-minute warning of each half, and in overtime, reviews can only take place if the replay assistant, who sits in the press box and monitors the network broadcast of the game, determines that a play needs review; coaches may not challenge during these times. In those cases, the replay assistant will contact the referee by a specialized electronic pager with a vibrating alert.
