Because the game isn't decided in the first half. When good teams (which is almost the entire Big East) buckle down, we buckle. Seton Hall, almost to a man, is more athletic, more physical, and more tough minded than our guys. They shot poorly from the field and the line, but found another way to win.
Talking about building a culture? First Willard and now Holloway have done that at Seton Hall. They are not bursting with talent, but they always play hard and very physical, and if you beat them, they usually make you earn it. You can see the difference in effort and tenacity between their players and ours. They didn't even celebrate their important road win like it was some kind of upset (they were slight underdogs). Seems like they knew what the outcome would be once they started playing tough defense and attacking the rim on offense.
