They lost because he sucks. Maybe he is slightly better as a passer. MAYBE. Leonard is significantly better runner and that diverse run game mixed with the pass is better than Penn St. Ultimately turnovers lost the game for them The same turnovers that beat 2 weak smaller schools.A better balanced offense by Penn State. Especially the passing game.
At the end of the day it was a tough game. Either side win or lose wasn't a bad play. Could play 100 times and split 50/50. Biggest difference was coaching and more diverse offense with ND
