For example, the greatest play to ever happen on the goal line is James Harrison's interception (which he returned 100 yards as the first half of Super Bowl XLIII expired).
We used the line of scrimmage as the point of reference for every play unless otherwise noted. So, Scott Norwood's historic game-losing 47-yard field goal miss would appear on the 30-yard line. But Tracy Porter's game-clinching interception of Peyton Manning would appear where he picked Peyton off. Capiche? Let the arguing begin.
