There comes a point at the start of every undefeated season where a fan has to rationalize what is happening in a most irrational way. The odds of running the table in college basketball are minuscule, but no fan wants his team to actually drop a game. As 6-0, 8-0, 10-0 approach, he has to decide if losing now so as not to be undefeated entering the tournament is worth it. This, of course, makes little actual sense in the cold light of day, but it happens.
Xavier is now 6-0 and has gotten there without two key players and without playing particularly good basketball all the time.
