Katz's upset pick of the week

Gonzaga wins at Xavier (Saturday, 8 p.m. ET on ESPN2): I might regret this pick, but something seems amiss with Xavier, which recently fell out of the Top 25. And it’s not just the absence of Dez Wells or Mark Lyons for two games in Hawaii. The Musketeers have lost their edge a bit since the fight broke out in its Dec. 10 win against Cincinnati; Gonzaga’s visit is a crucial game to get it back. The Zags come into this New Year's Eve matchup with a renewed sense of self after a spirited win against Butler.
