It was bound to happen. After all, N.C. State wide receiver Koren Robinson set a conference record for freshman receiving yardage last season. Factor in new coach Chuck Amato's pass-oriented attack and the arrival of strong-armed freshman quarterback Philip Rivers, and one would assume big numbers from Robinson this year. But no one knew exactly how big those numbers would be. Robinson has terrorized opposing secondaries this season, averaging a gaudy 120.2 receiving yards per game, good for second in the nation.
