If you're not familiar with the Law of Gus - this is an excellent primer. Whenever commentator GUs Johnson calls a game, something amazing happens. Case in point, this remarkable 77-yard run by Nebraska qb Taylor Martinez, which is actually more like 90 when you count his backwards run. You know something golden is happening when GUs roars - "He's got a lane".
Notice the burst of acceleration around the 50 yard line and the casual way he avoids the leg of his own blocker near the 5 yard line.
