And then there were none.
Behind strong efforts from DeAndre Ayton, Allonzo Trier and Dusan Ristic, Arizona held off a ferocious late charge from Arizona State to hand the Sun Devils their first loss of the season, 84–78, in Tucson on Saturday night. ASU entered the day as one of three remaining undefeated teams in college basketball—Villanova and TCU were the others—but all three fell before the day's end to leave the sport with zero unbeaten teams entering 2018.
Exactly how rare is this? A year ago, Matt Norlander of CBSSports.com researched when the last remaining undefeated team lost in each of the past 25 seasons, and none of those losses came before the turn of the calender year.
