OMAHA, Neb. — Gonzaga’s Zach Norvell Jr. got off to a slow start against Creighton for the second year in a row. Like last year, he finished with a flurry. Norvell scored 23 of his career-high 28 points in the second half, and top-ranked Gonzaga wiped out an early double-digit deficit and beat Creighton 103-92 on Saturday. Norvell’s shot was off throughout the first 20 minutes.
