<< If the ball passes the line of scrimmage (which it did) you'll have a hard time getting that call. Much like when a quarterback throws an obious uncatchable ball out of the endzone or out of bounds. The key here is that it passed the line of scrimmage. >>
In this case, however, the ball was a good 15 yards behind the nearest receiver. The only time "passed the line of scrimmage" counts is if the QB is outside the tackles. As for Madden and Summerall missing this point, it doesn't surprise me. Anyone count the number of times Summerall called Warner "Favre"?
Also, to quote the official NFL rules (under Timing):
<< 1. The stadium game clock is official. In case it stops or is operating incorrectly, the Line Judge takes over the official timing on the field. >>
So, the clock on the field read 2 seconds, the game was not over. The clock keeper in the stadium goofed and let the time run off. There was time for a kickoff. As to whether or not it would have mattered, it definitely could have. The Rams have very talented return specialists. It's a long shot, but it is the Super Bowl and the Rams deserved at least the chance.
