At the risk of giving NU more credit than they deserve, USC was the luckiest team I've seen in a long time. In order.
On their first TD: They complete a miracle pass on 2nd and 13th that had probably a 1% chance of completing. Desperation heave that they complete for 1st and goal instead of 3rd and 13.
Their 2nd TD: Friggin unreal TD on 2nd and goal from the 12 on a pass that Hartzog tipped, then had it ricochet off his helmet into the WR hands. TD instead of 3rd and goal from the 12.
Official blow an obvious DPI that would have given NU first and goal at the 1. Two officials watching Banks' feet and oblivious to one of the easiest PI calls they'd ever have to make. Clowns. NU gets 3 instead of 4 cracks at 7 from the 1.
On USC's final TD drive: First, they snap the ball into the leg of receiver gong in motion, get lucky to recover the fumble on this Nebraska-like bungled play. Then, on the very next play, their QB's arm is hit as he throws, resulting in a wobbly fumble/pass that is tipped and ONCE AGAIN RICOCHETS OFF AN NU HELMET. into the arms of their receiver for 9 yards. 4th and a foot instead of 4th and 9th and a punt.
Of course, not to be outdone by the first missed DPI, the clown show officials miss an even easier DPI on the games final play. It was bad enough that the DB was grabbing Banks' jersey during the entire sequence, he literally yanked Banks backwards, preventing him from making any kind of play on the ball.
NU deserves no sympathy for yet another season crumbing down the stretch, but JFC, USC was lucky as hell yesterday.
